Dear Stockholder,

You are cordially invited to attend the annual meeting of stockholders (“Annual Meeting”) of Clean Energy Fuels Corp. (the “Company,” “Clean Energy,” “we,” “us” or “our”) on Monday, June 14, 2021,Thursday, May 19, 2022, at 9:8:00 a.m. Pacific Time. The Annual Meeting will be a virtual meeting conducted via live audio webcast that can be accessed by visiting www.virtualshareholdermeeting.com/CLNE2021CLNE2022. At this website, you will be able to listen to the Annual Meeting live, submit questions for our management, directors and representatives of our independent registered public accounting firm in attendance, and submit your vote while the Annual Meeting is being held.

2021 turned out to be one of the most groundbreaking in the Company’s history. We are excited about the Annual Meeting, particularly because it providesbelieve our stockholders an opportunitydecision to approverapidly accelerate our renewable natural gas (RNG) offering will play a component of what we believe is an important commercial partnership for Clean Energy. On April 16, 2021, big role in connection with entering into a Project Addendumour customers’ ability to Fuel Pricing Agreement (the “Fuel Agreement”) with a subsidiary of Amazon.com, Inc. (“Amazon”), we entered into a Transaction Agreement with Amazon under which we issued to another subsidiary of Amazon a warrant (the “Amazon Warrant”) to purchase up to an aggregate of 53,141,755 shares of our common stock at an exercise price of $13.49 per share, which was 21.3% more than the $11.12 closing price of our common stock on April 15, 2021.

Through the Fuel Agreement and Amazon Warrant, our board of directors (the “Board”) believes Amazon can become an important strategic partner for Clean Energy. Further, Amazon is purchasing low and negative carbon Renewable Natural Gas (“RNG”) from Clean Energy, which we believe validates using RNG as a transportation fuel at scale.

achieve their sustainability goals by significantly reducing greenhouse gas emissions produced by their fleets.

We expect to providebe able to meet the growing demand for this incredibly clean fuel well into the future by investing in the production of additional RNG sources with our joint venture partners, TotalEnergies and bp. We cemented these two joint ventures in early-2021 and quickly went to Amazon through 27 existing fueling stationswork signing partnerships with dairy owners around the country. I had the privilege of meeting with a number of them and 19 non-exclusive newmost, if not all, are family run dairy farms with multiple generations involved in the operations. These are hard-working men and women who have a passion to run their operations in the most environmentally-friendly way. The idea of turning the manure from their cows into a clean fuel that will operate fleets of refuse trucks, city buses or upgraded stations that we expectheavy-duty trucks is very appealing to construct by the endthem.
The additional RNG from these dairies, which is rated cleaner than even electric vehicles, will allow us to expand our current customer roster, which includes some of the year. The newlargest fleets in the country like Amazon, UPS, Republic Services and existing stations will provide RNGthe transit agencies in 15 different states across the United States,New York City and we will own all the stations.

The Warrant Shares vest in multiple tranches,Los Angeles.

As exciting and active as 2021 was, I am even more optimistic about 2022, which marks Clean Energy’s 25th anniversary. We were one of the first companies to offer transportation fleets a solution to tackle the problem of which for 13,283,445 Warrant Shares vested upon execution ofdirty air and now we’re giving them a powerful tool to address the Fuel Agreement. Subsequent tranches will vest over time based on fuel purchases by Amazon and its affiliates, up to a total of $500 million, excluding any payments attributable to “Pass Through Costs,” which consist all costs associated with the delivered cost of gas and applicable taxes determined by reference to the selling price, gallons or gas sold. Importantly, if all the vesting conditions of the Amazon Warrant are satisfied, Amazon will have purchased hundreds of millions of gasoline gallon equivalents (“GGEs”) of RNG at today’s fuel prices from Clean Energy.

We believe a commercial partnership with Amazon will enhance our strategies, initiatives and efforts to achieve our goals to grow fleet and other consumer support for the use of RNG as a vehicle fuel for our target customers and geographies. The Board also believes the proceeds from the issuanceissue of our common stock to Amazon in the event Amazon were to vest and then exercise the Amazon Warrant in part or whole for cash, would enhance our liquidity in support of our operations, as well as our ability to execute our business plans and pursue opportunities for further growth. Accordingly, we believe securing this commercial partnership and incenting Amazon to purchase the maximum amount of fuel under the Fuel Agreement is important for the trajectory of Clean Energy.

Our Board approved the Fuel Agreement and Amazon Warrant, and recommends our stockholders approve the Amazon Warrant as described in these proxy materials. Further, all independent Board members and senior executive officers (including myself) have agreed to vote our shares in favor of the transaction.

changing climate with RNG.

We are pleased to take advantage of laws and rules that allow issuers to make use of the Internet in conducting a meeting of stockholders, as well as in furnishing proxy materials. As a result, we will not only host the Annual Meeting virtually on the Internet, but we will also furnish the proxy materials for the Annual Meeting to our stockholders on the Internet.

Virtual Annual Meeting
We have held our annual meetings of stockholders virtually since 2017, and we have again elected to hold this year’s Annual Meeting virtually on the Internet. We have made this decision for a number of reasons, including:

·The attendance at our most recent in-person stockholder meetings was low, consisting of an average of 12 stockholders who attended each of our most recent three meetings in person. The most recent such meeting was in 2017, when we held a “hybrid” meeting that included both in-person and virtual access to the meeting. Despite these historically low in-person attendance levels, offering in-person access to our stockholder meetings can involve significant costs, including monetary expenses and increased management and employee time. As a result, we determined that offering in-person access to the Annual Meeting would not provide sufficient benefits to our stockholders to justify the associated costs.

·Attendance at our stockholder meetings held in 2019 and 2020, both of which included a virtual component, increased substantially. The number of stockholders who attended each of these meetings via the Internet rose to an average of 29 stockholders per meeting. In light of this increase in average attendance, we believe the virtual meeting format, which allows our stockholders to attend meetings from their locations around the world, is an effective way to encourage and enable more of our stockholders to participate in our annual meeting process. As a result, we determined to host the Annual Meeting virtually in order to support similar or further increased stockholder attendance levels at this year’s meeting.

·Stockholders who attend the Annual Meeting virtually will be able to listen to the meeting live and submit their vote while the Annual Meeting is being held, and will also be able to submit, either anonymously or identified by name, questions or comments for our management, directors and representatives of our independent registered public accounting firm in attendance at the meeting. This functionality provides our stockholders with opportunities for participation and engagement at the Annual Meeting that are comparable to those that would be available at an in-person meeting. As a result, we believe the virtual nature of the Annual Meeting will not decrease engagement capabilities and could facilitate increased stockholder participation with the ability to submit comments and questions anonymously if a stockholder desires to do so.

·During the Annual Meeting, we will answer as many stockholder-submitted questions as time permits, other than questions that are irrelevant to the purpose of the Annual Meeting or our business or that contain inappropriate or derogatory references that are not in good taste. Any appropriate questions that we are unable to address during the Annual Meeting will be published on our website following the meeting. If we receive substantially similar questions, we will group them together and provide a single response to avoid repetition.

·We are sensitive to the public health and travel concerns stockholders may have regarding the coronavirus (COVID-19) and the protocols that federal, state and local governments are imposing. Accordingly, we believe that holding this year’s Annual Meeting virtually is prudent in order to mitigate the health and safety risks to our stockholders while also facilitating stockholder attendance and participation at the Annual Meeting.


The attendance at our most recent in-person stockholder meetings was low, consisting of an average of 12 stockholders whom attended each of our three most recent in person meetings. The most recent such meeting was in 2017, when we held a “hybrid” meeting that included both in-person and virtual access to the meeting. Despite these historically low in-person attendance levels, offering in-person access to our stockholder meetings can involve significant costs, including monetary expenses and increased management and employee time. As a result, we determined that offering in-person access to the Annual Meeting would not provide sufficient benefits to our stockholders to justify the associated costs.

Attendance at our stockholder meeting held in 2021, which included a virtual component, increased substantially. The number of stockholders who attended our 2021 annual meeting of stockholders via the Internet rose to 455 stockholders. In light of this increase in attendance, we believe the virtual meeting format, which allows our stockholders to attend meetings from their locations around the world, is an effective way to encourage and enable more of our stockholders to participate in our annual meeting process. As a result, we determined to host the Annual Meeting virtually in order to support similar or further increased stockholder attendance levels at this year’s meeting.

Stockholders who attend the Annual Meeting virtually will be able to listen to the meeting live and submit their vote while the Annual Meeting is being held, and will also be able to submit, either anonymously or identified by name, questions or comments for our management, directors and representatives of our independent registered public accounting firm in attendance at the meeting.

Stockholders who choose to attend the Annual Meeting will do so by accessing a live audio webcast of the Annual Meeting via the Internet at www.virtualshareholdermeeting.com/CLNE2021CLNE2022. Please see “Attending the Virtual Annual Meeting” below for more information.

Record Date and Outstanding Shares

All stockholders that owned shares of our common stock at the close of business on April 19, 2021,March 22, 2022, the date fixed by the Board as the record date, are entitled to vote at the Annual Meeting.

On the record date, 199,857,559222,713,200 shares of our common stock were outstanding.

Voting Matters

Voting Rights

Each share of our common stock entitles the owner of the share to one vote on all matters to be voted on at the Annual Meeting.


2


Quorum Requirement

We will have the required quorum to conduct the business of the Annual Meeting if holders as of the record date representing a majority of the outstanding shares of our common stock entitled to vote are present in person or represented by proxy at the Annual Meeting. Abstentions and broker non-votes (discussed under “Effect of Not Providing Voting Instructions; Broker Non-Votes” below) will be counted for purposes of determining the presence of a quorum at the Annual Meeting.

Effect of Not Providing Voting Instructions; Broker Non-Votes

Stockholders of Record.You are a “stockholder of record” if your shares are registered directly in your name with Computershare Trust Company, N.A., our transfer agent. If you were a stockholder of record at the close of business on the record date for the Annual Meeting and you submit a valid proxy but do not provide voting instructions with respect to your shares, all shares represented by your proxy will be voted in accordance with the recommendation of our Board on each proposal to be presented at the Annual Meeting, as described in this Proxy Statement.

Beneficial Owners of Shares Held in Street Name.You are a “beneficial owner of shares held in street name” if your shares are not held of record in your name but are held by a broker, bank or other nominee on your behalf as the beneficial owner. Pursuant to applicable stock exchange rules, if your shares were held in street name through a brokerage account at the close of business on the record date for the Annual Meeting, you must provide voting instructions to your broker if you want your shares to be voted on the election of directors (Proposal 1), the approval, on an advisory, non-binding basis, of the compensation of our named executive officers (Proposal 3), and the approval, for the purpose of complying with Nasdaq Listing Rule 5635(b), of the issuance of shares of our common stock upon exercise of the Amazon WarrantNew ESPP (Proposal 4). These proposals constitute “non-routine” matters on which a broker is not entitled to vote shares held for a beneficial owner without receiving voting instructions from the beneficial owner. The ratification of the appointment of KPMG LLP as our independent registered public accounting firm (Proposal 2) and the approval of an amendment to our Restated Certificate of Incorporation to increase the authorized shares of our common stock (Proposal 5) areis considered a “routine” mattersmatter for which your shares may be voted in the discretion of your broker if voting instructions have not been received. As a result, if you hold your shares in street name and you do not submit voting instructions to your broker, your broker may exercise its discretion to vote on Proposal 2 and Proposal 5 at the Annual Meeting but will not be permitted to vote on Proposal 1, Proposal 3 or Proposal 4 at the Annual Meeting. In recent years, however, several large brokers, such as Charles Schwab and TD Ameritrade have announced that they have eliminated discretionary voting for even “routine” matters. Therefore, if you hold your shares through such brokers, then your shares might not be voted, even for “routine” matters if you do not give voting instruction to your broker. Therefore, we urge every stockholder to vote their shares. If your broker exercisesdoes exercise this discretion, your shares will be counted as present for determining the presence of a quorum at the Annual Meeting and will be voted on Proposal 2 and Proposal 5 in the manner directed by your broker, but your shares will constitute “broker non-votes” on each of the other items at the Annual Meeting. Moreover, if you are a beneficial owner of shares in street name and you properly submit a voting instruction form to your broker, bank or other nominee that is signed but unmarked with respect to your vote on Proposals 1, 2, 3 4 or 5,4, applicable rules will generally permit your broker, bank or other nominee to vote your shares on these proposals in accordance with the recommendations of the Board as set forth in this Proxy Statement.


Voting Requirements

The election of directors (Proposal 1) will be determined by a plurality of the votes cast on the proposal at the Annual Meeting. This means that the nineten nominees who receive the highest number of affirmative votes will be elected as directors. Shares voted “Withhold” and broker non-votes are not counted as votes cast and will have no effect on the outcome of the election of directors.

The ratification of the appointment of KPMG LLP as our independent registered public accounting firm (Proposal 2), the approval, on an advisory, non-binding basis, of the compensation of our named executive officers (Proposal 3), and the approval, for the purpose of complying with Nasdaq Listing Rule 5635(b), of the issuance of shares of our common stock upon exercise of the Amazon WarrantNew ESPP (Proposal 4) must each be approved by the affirmative vote of a majority of the votes cast on the proposal at the Annual Meeting. For purposes of determining the number of votes cast for Proposals 2, 3 and 4, only shares voted “FOR” or “AGAINST” are counted. Abstentions and broker non-votes are not treated as votes cast and will not be counted in determining the outcome of Proposal 2, Proposal 3 or Proposal 4.

The approval of an amendment to our Restated Certificate of Incorporation to increase the authorized shares of our common stock (Proposal 5) must be approved by the affirmative vote of the holders of a majority of the issued and outstanding shares of our common stock entitled to vote on the proposal at the Annual Meeting. Abstentions will have the same effect as a vote against Proposal 5. Because Proposal 5 is expected to be a “routine” matter for which you shares may be voted in the discretion of your broker if voting instructions have not been received, we do not expect any broker non-votes to occur on Proposal 5.

TABLE OF CONTENTS

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The two tables below show the beneficial ownership of certain persons with respect to our common stock, our only outstanding class of voting securities. Except as indicated by the footnotes to these tables, we believe, based on the information furnished or otherwise available to us, that the persons and entities named in these tables have sole voting and investment power with respect to all shares of common stock shown as beneficially owned by them, subject to applicable community property laws.

We have determined beneficial ownership as shown in these tables in accordance with the rules of the SEC. In accordance with these rules, in computing the number of shares of our common stock beneficially owned by a person and the percentage ownership of that person, we deemed to be outstanding all shares of our common stock subject to (1) stock options held by that person that are currently exercisable or exercisable within 60 days after April 19, 2021,March 22, 2022, and (2) restricted stock units (“RSUs”) held by that person that are subject to vesting and settlement within 60 days after April  19, 2021.March 22, 2022. We did not, however, deem these shares outstanding for the purpose of computing the percentage ownership of any other person. We calculated percentage ownership as shown in these tables based on 199,857,559222,713,200 shares of our common stock outstanding on April 19, 2021.March 22, 2022. The information in these tables is not necessarily indicative of beneficial ownership for any other purpose, and the inclusion of any shares in these tables does not constitute an admission of beneficial ownership of the shares.

The following table shows the amount and percentage of our common stock beneficially owned by each holder of more than 5% of the outstanding shares of our common stock:

Selecting Our Director Nominees

Under its charter and our corporate governance guidelines, our nominating and corporate governance committee is responsible for reviewing with the Board, on an annual basis, the requisite skills and characteristics of potential new Board members, as well as the composition of the Board as a whole. This assessment includes an analysis of each member’s qualifications as a director and each member’s independence, as well as consideration of age, experience and other diversity factors in the context of the needs of the Board.


Minimum Criteria

Pursuant to our corporate governance guidelines, a majority of our directors must meet the standards for independence as required by Nasdaq, and no director may serve on more than three other public company boards of directors unless approved in advance by the Board. Further, applicable Nasdaq rules provide that at least one member of our Board must meet the criteria for an “audit committee financial expert” as defined by SEC rules, and the members of certain of our Board committees must satisfy enhanced independence and financial expertise standards under applicable Nasdaq and SEC rules. We also believe all directors should possess the following attributes:

·
Professional ethics and values, consistent with our code of ethics (described below under “Corporate Governance—Governance — Code of Ethics”);


·12

TABLE OF CONTENTS


A commitment to building stockholder value;

·
Business acumen and broad experience and expertise at the policy-making level in one or more of the areas of particular consideration described under “Key Qualifications, Skills and Attributes” below;

·
The ability to provide insights and practical wisdom based on the individual’s experience or expertise; and

·
Sufficient time to effectively carry out duties as a Board member.

Other than the foregoing, there are no stated minimum criteria for director nominees, and the nominating and corporate governance committee may consider these factors and any such other factors as it deems appropriate. The nominating and corporate governance committee does, however, review the activities and associations of each potential director candidate to ensure there is no legal impediment, conflict of interest or other consideration that might hinder or prevent service on our Board.

Diversity

Although we do not have a formal policy with respect to Board diversity, the nominating and corporate governance committee strives to assemble a board of directors that brings to our Company a variety of perspectives, skills and expertise. To achieve this, the nominating and corporate governance committee considers individuals from various disciplines and backgrounds in recommending director nominees to the Board, including diversity characteristics that may be self-identified by directors or director nominees, such as race, gender, military service, or other socioeconomic or demographic characteristics. The nominating committee also seeks to recommend directors who possess a broad range of business, professional, governmental, community involvement and natural gas and energy industry experience.

The nominating and corporate governance committee assesses these and other factors as it deems appropriate in connection with its annual review of each director and the Board as a whole and takes these factors into account when determining whether to nominate existing directors for re-election in connection with this annual review. The nominating and corporate governance committee also takes these factors into account when considering any director nominee outside of its annual review process, such as when a vacancy exists on the Board or when a stockholder suggests a new director candidate that the committee or the Board decides to consider for a mid-year appointment. In addition, as part of its annual self-evaluation process, the nominating and corporate governance committee assesses its consideration of diversity in identifying and evaluating director candidates, including the key qualifications, skills and attributes that it aims for directors to possess.

The nominating and corporate governance committee is committed to further diversifying the Board across a number of metrics, including gender and representatives of underrepresented communities. In September 2018, California enacted a law requiring publicly held corporations whose principal executive offices are located in California to have at least one female director on their boards by the end of the 2019 calendar year and, if ourOur Board maintains its existing size, at leastappointed three female directors by the end of the 2021 calendar year. On September 30, 2020, California enacted a law requiring California-headquartered public companies to have at least one director on its board from an underrepresented community, and if our Board maintains its existing size, at least three directors from underrepresented communities by the end of calendar year 2022. Because our principal executive offices are located in California, the nominating and corporate governance committee intends to comply with the requirements of these laws on or before the applicable deadlines. Our Board appointedsince 2019, including Ms. Lizabeth Ardisana female Hispanic business owner, as a director in December 2019 and the nominatingeach of Ms. Karine Boissy-Rousseau and corporate governance committeeMs. Lorraine Paskett in December 2021. Three of our ten directors are female and two of our ten directors self-identify as an “underrepresented minority” as such term is actively reviewing and evaluating a number of potential female director candidates and candidates from underrepresented communities for appointment or election at a future date.

defined by Nasdaq Listing Rule 5605(f).

Board Refreshment

Board members with a diversity of life experiences, backgrounds and gender are important to bring a variety of perspectives to our Board, as discussed above under “Diversity.” We aim to regularly bring new directors to our Board at a responsible pace to ensure the Board benefits from fresh ideas and perspectives, while balancing the importance of directors who have experience with our Company.

Board refreshment is a key matter considered during our annual Board and committee self-evaluations. InWe have refreshed a majority of our Board since 2018, we added Momar Nguerincluding the retirement of three long-tenured directors and Philippe Montantême to the Board. Also, in 2018 T. Boone Pickens, our co-founder, retired from his position as an active director and became a director emeritus, an honorary position in recognitionappointment of his long-standing, loyal and dedicated services and singularly significant contributions to the Company; Mr. Pickens held such honorary position until passing away in September 2019. Lizabeth Ardisana joined the Board in 2019. In 2020 Mr. Nguer was replaced by Phillippe Charleux, long-time directors Warren Mitchell and James O’Connor retired from the Board, and Parker Weil was added to the Board. In 2021 Thomas Maurisse replaced Philippe Montantême; John Herrington, an original director, retired from the Board. We are grateful to all our former directors for their exemplary service. Other long-time directors may retire, and we expect to add one or more additionalthree female directors before the endsince 2020. The average tenure of 2021.

our Board members is eight (8) years.

Key Qualifications, Skills and Attributes

The nominating and corporate governance committee regularly reviews the appropriate skills and characteristics required of Board members in the context of the composition of the Board, our operating requirements, and the long- termlong-term interests of stockholders. When conducting its review of the key qualifications, skills and attributes desired of Board members, the nominating and corporate governance committee particularly considers:


Senior Leadership Experience:

Board members who have served in senior leadership positions, such as a chief executive officer, chairman, senior executive, or leader of significant operations, are important to us because they have the experience and perspective to analyze, shape and oversee the execution of important strategic, operational and policy issues. These Board membersmembers’ insights and guidance, and their ability to assess and respond to situations encountered by our Board, may be enhanced by leadership experience at complex businesses or organizations.

RNG and Conventional Natural
Gas and Industry Experience:

Because we are seeking to drive adoption of RNG and conventional natural gas as a vehicle fuel by fleet vehicle operators, primarily in the trucking, airport, refuse, public transit, industrial and institutional energy user and government fleet markets, relevant education or experience in our industry is key for understanding our markets, strategy, risk management and operations.

Government, Legal, Public Policy and Regulatory Expertise:

Board members who have served in government positions provide experience and insights that help us work constructively with governments and address significant public policy issues. Board members with a background in law can assist the Board and legal team in fulfilling its oversight responsibilities regarding our legal and regulatory compliance and our engagement with regulatory authorities.

Financial Expertise:

Knowledge of financial markets, financing and funding operations and accounting and financial disclosure and reporting processes is important to have well-represented on our Board. This experience helps our Board members in understanding and overseeing our capital structure, financing and investing activities, as well as our financial reporting and internal controls.

Public and Private Company
Board Experience:

Board members with public and private company board experience understand the dynamics and operations of a corporate board. These matters include the relationship of a company board with senior management personnel, the legal and regulatory landscape in which companies must operate, the importance of particular agenda and oversight issues, and how to oversee an ever-changing mix of strategic, operational and compliance-related matters.

From time to time, the nominating and corporate governance committee will also consider such other qualifications, skills and attributes as it deems appropriate given the needs of the Board and the Company to maintain a balance of knowledge, experience, background and capability.

Director Nominee Evaluations

At least annually, our nominating and corporate governance committee leads an evaluation of each of our directors and our Board as a whole and each of its committees. In evaluating whether a current director should continue to serve on our Board, the nominating and corporate governance committee considers a number of factors, including the minimum criteria and diversity goals described above and each director’s qualifications, skills and attributes in the areas identified by the committee as particularly important to our Board. In concluding that each of the director nominees should continue to serve as directors of the Company, the nominating and corporate governance committee considered their knowledge, experience and

expertise in these areas as indicated in the table below, which they gained from their professional backgrounds described under “Director Nominees” above.

PROPOSAL 3

ADVISORY, NON-BINDING VOTE TO APPROVE EXECUTIVE COMPENSATION

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank Act”) enables our stockholders to vote to approve, on an advisory, non-binding basis, the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the SEC’s compensation disclosure rules.

As described in detail under “Compensation Discussion and Analysis” below, our executive compensation program is designed to attract, retain and motivate talented and dedicated executive officers; to reward individual performance and achievement of key corporate objectives without promoting excessive or unnecessary risk-taking; to align the interests of our executives with those of our stockholders; and to provide compensation that we believe is fair in light of an executive’s experience, responsibilities, performance and tenure with our Company and in relation to the compensation provided to other executives of our Company and certain peer companies. Under this program, determinations regarding each named executive officer’s compensation are based on, among other factors, the individualsindividual’s performance and contribution to our strategic plans and other business objectives; the CompanysCompany’s overall performance, in light of business and industry conditions; general industry benchmarks and trends, including the compensation practices of certain peer companies; the level of the individualsindividual’s responsibility; the seniority of the individual; the individualsindividual’s long-term commitment to our Company; the available pool of individuals with similar skills; principles of pay equity and relative pay; the role of each compensation component in achieving the objectives of our executive compensation program; and the compensation committeescommittee’s business judgment and experience. Please read the “Compensation Discussion and Analysis” beginning on page 4132 for additional details about our executive compensation program.

We are asking our stockholders to indicate their support for our named executive officer compensation as described in this Proxy Statement. We believe the compensation of our named executive officers is appropriate and serves to both incentivize and retain our highly skilled executive leadership team. Attracting, retaining and motivating key executives is crucial to our success. This say-on-pay proposal gives our stockholders the opportunity to indicate whether they approve of our named executive officers’ compensation. This vote is not intended to address any specific component of compensation, but rather relates to the overall compensation of our named executive officers and our executive compensation philosophy, policies and practices described in this Proxy Statement in accordance with the SEC’s compensation disclosure rules. Accordingly, we ask that our stockholders vote “FOR” the following resolution at the Annual Meeting:

“RESOLVED, that the Company’s stockholders approve, on an advisory, non-binding basis, the compensation of the Company’s named executive officers, as disclosed in the Company’s Proxy Statement for its 20212022 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other related tables and disclosure included therein.”

This say-on-pay proposal is being provided as required by Section 14A of the Exchange Act and is advisory and therefore not binding on the Company, the compensation committee or our Board in any way. Our Board and our compensation committee value the opinions of our stockholders, and to the extent there is any significant vote against the named executive officer compensation as disclosed in this Proxy Statement, we will consider our stockholders’ concerns and the compensation committee will evaluate whether any actions are necessary to address these concerns.

Our current policy is to provide stockholders with an opportunity to vote on the compensation of our named executive officers each year at the annual meeting of stockholders. It is expected that the next such advisory vote will occur at the 20222023 annual meeting of stockholders.

PROPOSAL 4

APPROVAL FOR THE PURPOSE OF COMPLYING WITH NASDAQ LISTING RULE 5635(b), OF THE ISSUANCE OF SHARESCOMPANY’S
OF OUR COMMON2022 EMPLOYEE STOCK UPON EXERCISE OF THE AMAZON WARRANT

Background

On April 16, 2021, in connection with executionPURCHASE PLAN

General
At the Annual Meeting, stockholders will be asked to approve the 2022 Employee Stock Purchase Plan and the reservation of the Fuel Agreement with a subsidiary of Amazon, we entered into the Transaction Agreement with Amazon under which, among other things, we issued the Amazon Warrant to another subsidiary of Amazon to purchase up to an aggregate of 53,141,7552,500,000 shares of our common stock for issuance under the New ESPP. The New ESPP was adopted by the Board, subject to stockholder approval, on April 6, 2022.
The Company currently maintains the Clean Energy Fuels Corp. Employee Stock Purchase Plan (the “Old ESPP”). As of March 15, 2022, a total of 1,796,912 shares of common stock were available for new option grants under the Old ESPP, before giving effect to outstanding purchase rights for the currently in-progress offering period that will end on June 30, 2022. If stockholders approve the New ESPP, the Old ESPP will terminate following the conclusion of the currently in-progress offering period on June 30, 2022, and the shares available under the Old ESPP will no longer be available for option awards under either the Old ESPP or the New ESPP (i.e., the New ESPP does not have a “pour over” feature). If stockholders do not approve the New ESPP, the Company will continue to have the authority to grant new options under the Old ESPP until the term of the Old ESPP expires in 2023. If stockholders approve the New ESPP, the first offering period under the New ESPP is expected to begin on July 1, 2022.
Under the New ESPP, shares of the Company’s common stock will be available for purchase by eligible employees who elect to participate in the New ESPP. Eligible employees will be entitled to purchase, by means of payroll deductions, limited amounts of the Company’s common shares during periodic “Offering Periods” as described below at a discount from the then current market price. The Board believes that the New ESPP will continue to help the Company retain and motivate eligible employees and will continue to help further align the interests of eligible employees with those of the Company’s stockholders. No purchase rights will be exercised and no shares will be issued under the New ESPP without stockholder approval.
A general description of the New ESPP is set forth below. This description is qualified in its entirety by the terms of the New ESPP, a copy of which is attached to this Proxy Statement as Annex A.
Administration
It is anticipated the compensation committee will serve as the Plan Administrator, and as such will have full authority to adopt such rules and procedures as it may deem necessary for proper plan administration and to interpret the provisions of the New ESPP.

A total of 2,500,000 shares of common stock are authorized for purchase over the term of the New ESPP, subject to adjustment and vesting in accordance with the terms and conditions set forth in the Amazon Warrant.

Our Board recommends that ourevent of a stock split, stock dividend, combination or reclassification or similar event. If stockholders approve our issuancethe New ESPP, the Old ESPP will terminate following the conclusion of the currently in-progress offering period on June 30, 2022, and the shares available under the Old ESPP will no longer be available for option awards under either the Old ESPP or the New ESPP (i.e., the New ESPP does not have a “pour over” feature).

Offering Periods
The New ESPP is expected to be implemented through two offering periods per calendar year, with each offering period lasting six months. The Plan Administrator may alter the duration of future offering periods in advance without stockholder approval. Each participant is granted a separate purchase right to purchase shares of our common stock for each offering period in excesswhich he or she participates. Purchase rights under the New ESPP are granted on the start date of 50,595,531 shares (the “Share Cap”) pursuant to,each offering period in which the participant participates and upon exerciseare automatically exercised on the last day of the Amazon Warrant, in orderoffering period. Each purchase right entitles the participant to ensure such issuance complies with Nasdaq Listing Rule 5635(b). The Share Cap representspurchase the highestwhole number of shares of our common stock obtained by dividing the participant’s payroll deductions for the offering period by the purchase price in effect for such period.

Eligibility
Except as described in this paragraph with respect to certain foreign employees, all employees of the Company and its subsidiaries are eligible to participate in the New ESPP, except that can be issued pursuantthe Plan Administrator may exclude from an offering period any individual who is regularly expected to work less than twenty hours per week or less than five months per calendar year in the Amazon Warrant without potentially requiringemploy of the Company or any subsidiary, any individual who has been employed less than 2 years, and certain highly compensated employees of the Company or any subsidiary. An eligible employee may only join an offering period on the start date of that period. Subsidiaries include any subsidiary corporation of the Company, whether now existing or hereafter organized, which elects, with the approval of our stockholders under Nasdaq Listing Rule 5635(b). We filed a copythe Plan Administrator, to extend the benefits of the Amazon Warrant as Exhibit 4.4New ESPP to our Current Report on Form 8-Ktheir eligible employees. Employees who are citizens or residents of a non-U.S. jurisdiction (without regard to whether he or she is also a citizen of the United States or a resident alien (within the meaning of Section 7701(b)(1)(A) of the Internal Revenue Code of 1986 (“Code”)) are ineligible to participate in the New ESPP if his or her participation is prohibited under the laws of the applicable non-U.S. jurisdiction or if complying with the SEC on April 19, 2021. You are encouraged to read the full textlaws of the Amazon Warrant and such report. The below summaryapplicable non-U.S. jurisdiction would cause the New ESPP or an offering to violate Section 423 of the Amazon WarrantCode.
As of March 15, 2022, 4 executive officers and related transactions does not purportapproximately 437 other employees were expected to be completeeligible to participate in the New ESPP.
Purchase Provisions
Each participant in the New ESPP may authorize periodic payroll deductions that may not exceed the lesser of (i) 10% of his or her compensation, which is defined in the New ESPP to include his or her regular base salary in effect at the beginning of the offering period, exclusive of any payments for overtime, bonuses, annual awards, other incentive payments, reimbursements of expense allowances, fringe benefits (cash or non-cash), moving expenses, deferred compensation, or contributions (other than contributions under a 401(k) or cafeteria plan) and is subject(ii) such lesser amount determined by the Plan Administrator per offering period. A participant may increase or reduce his or her rate of payroll deductions during an offering period.
On the last day of each offering period, the accumulated payroll deductions of each participant are automatically applied to the full textpurchase of shares of common stock at the purchase price in effect for that period.
Purchase Price
The purchase price per share at which common stock is purchased on the participant’s behalf for each offering period is equal to 85% of the Amazon Warrant.

The Amazon Warrant and Related Agreements

The Warrant Shares vest in multiple tranches, the first of which for 13,283,445 Warrant Shares vested upon executionfair market value per share of the Fuel Agreement. Subsequent tranches can vest over time based on discretionary fuel purchases or other spending by Amazon and its affiliates, up to a total of $500 million. Subject to vesting and certain other conditions, the Amazon Warrant may be exercised, in whole or in part, at any time before April 16, 2031 at an exercise price of $13.49 per share, which was determined based on the 30-day volume-weighted average price of our common stock as of April 15, 2021, and is 21.3% more than the $11.12 closing price of our common stock on April 15, 2021, the last day prior to our issuance of the Amazon Warrant.

offering period.

Valuation
The Amazon Warrant may be exercised for cash or on a cashless basis. If Amazon were to vest and cash exercise part or allfair market value of the Amazon Warrant, we expect to use any net proceeds received from Amazon under the Amazon Warrant for working capital and general corporate purposes, which may include, among other purposes, executing our business plans, and pursuing opportunities for further growth. As of the date of this solicitation, however, we cannot specify with certainty all of the particular uses of such proceeds, if any, and we will have broad discretion over the use of any such proceeds. Pending our use of net proceeds, if any, we may invest the proceeds in short-term, interest-bearing, investment-grade securities.

Anti-Dilution Adjustments and Other Rights

Both the exercise price and the number of Warrant Shares subject to purchase under the Amazon Warrant are subject to customary anti-dilution adjustments, including as a result of any dividend or distribution of additional shares of our common stock or stock split, subdivision, combination or reclassification involving our common stock. Subject to certain exceptions, the exercise price and number of Warrant Shares issuable upon exercise of the Amazon Warrant are also subject to adjustment in connection with certain repurchases by us of our outstanding common stock. Further, in the event we issue, or commit to issue, any equity securities in a financing to raise capital within six months after the issuance of the Amazon Warrant, the number of Warrant Shares subject to the Amazon Warrant will be increased to a number that would represent 19.999% of our outstanding common stock on a fully diluted basis aftergiven date is the closing sales price of the common stock on the Nasdaq Global Select Market as of such date. As of March 15, 2022, the fair market value of a share of the Company’s common stock as reported on the Nasdaq Stock Market was $7.17.

Special Limitations
The New ESPP imposes certain limitations upon a participant’s right to acquire common stock, including the following limitations:

No purchase right may be granted to any individual who owns stock (including stock purchasable under any outstanding options or purchase rights) possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or any of its affiliates.

No purchase right granted to a participant may permit such individual to purchase common stock at a rate greater than $25,000 worth of such common stock (valued at the time such purchase right is granted) for each calendar year.

19


Termination of Purchase Rights
A participant’s purchase right immediately terminates upon such participant’s loss of eligible employee status, and his or her accumulated payroll deductions for the offering period in which the purchase right terminates are refunded. A participant may withdraw from an offering period by giving effectadvance notice prior to such financing (the “Financing Adjustment”).

the end of that period and his or her accumulated payroll for the offering period in which withdrawal occurs shall be refunded.

Assignability
No purchase right will be assignable or transferable (other than by will or the laws of descent and distribution) and will be exercisable only by the participant.
Corporate Transaction
In the event we make certain other specified dividends or distributions on shares of our common stock, Amazon Holdings will be deemed to have exercised the vested portion of the Warrant Shares and be entitledproposed dissolution or liquidation of the Company, the then-current offering period will terminate immediately prior to participate inthe consummation of such dividenddissolution or distribution.liquidation, unless otherwise provided by the Plan Administrator. In addition, in the event of a proposed sale of all or substantially all of the assets of the Company, certain mergers, an acquisition transactions involving us under conditions as set forthof a controlling interest in the Amazon Warrant, all unvested Warrant Shares will automatically vest and become exercisable.


Stockholder Approval Requirement

UnderCompany or a change in the termscomposition of a majority of the Transaction Agreement, we are requiredBoard following a contested election (each, a “Corporate Transaction”) during an offering period, all outstanding purchase rights shall be assumed by the successor corporation (or a parent or subsidiary thereof), unless the Plan Administrator determines, in its sole discretion, to use our commercially reasonable effortsshorten the offering period then in-effect to obtaina new purchase date. If the approval of our stockholders with respectPlan Administrator shortens the offering period then in progress to a new purchase date, the Plan Administrator will provide notice to each participant that (i) his or her purchase right will be automatically exercised on the new purchase date or (ii) the Company will pay to him or her, on the new purchase date, cash, cash equivalents, or property as determined by the Plan Administrator that is equal to the issuancedifference in the fair market value of the shares of our common stock covered by his or her purchase right and the purchase price due had the purchase right been automatically exercised on the new purchase date.

Changes in excess of the Share Cap (the “Stockholder Approval”), as may be required pursuant to Nasdaq Listing Rule 5635(b). Until the Stockholder Approval is obtained, Nasdaq Listing Rule 5635(b) may restrict the issuance of shares of our common stock exceeding the Share Cap pursuant to, and inCapitalization
In the event of an exercise of, the Amazon Warrant. In connection with obtaining the Stockholder Approval and under the Transaction Agreement, we agreedany change is made to file a proxy statement and hold a meeting of our stockholders as promptly as practicable to obtain the Stockholder Approval. If the Stockholder Approval is not obtained at a meeting of our stockholders called for such purpose, we are required, at Amazon’s request, to cause an additional meeting of stockholders to be held every twelve (12) months thereafter until either the Stockholder Approval is obtained or the term of the Amazon Warrant expires.

Support Agreements

In connection with the requirement for Stockholder Approval and pursuant to the terms of the Transaction Agreement, we have entered into Support Agreements by and among us, Amazon and each of our executive officers, members of our board of directors who are independent directors within the meaning of applicable rules of Nasdaq and the T. Boone Pickens Trust, under which each such stockholder has irrevocably agreed, among other things, to vote the number of shares of our common stock beneficially owned by such stockholder and for which he, she or it has or shares voting power in favor of the Stockholder Approval. Each stockholder’s agreements pursuant to the Support Agreement will continue until either the Stockholder Approval is obtained or the term of the Amazon Warrant expires. As of April 19, 2021, the record date for the Annual Meeting, an aggregate of 11,169,592 shares of our common stock, representing 5.6% of the outstanding shares of our common stock as of such date, were owned or controlled by our independent directors, executive officers and the T. Boone Pickens Trust and are subject to the Support Agreements.

Beneficial Ownership Limitation

Under the terms of the Amazon Warrant, Amazon.com NV Investment Holdings LLC (“Amazon Holdings”) as the holder of the Amazon Warrant may not exercise the Amazon Warrant to the extent such exercise would cause Amazon Holdings to beneficially own more than 4.999% of the number of shares of our common stock immediately outstanding after giving effect to such exercise (excluding any unvested portion of the Amazon Warrant) (the “Beneficial Ownership Limitation”). Amazon Holdings may, however, waive or modify the Beneficial Ownership Limitation by providing us written notice sixty-one (61) days before such waiver or modification becomes effective (or immediately upon written notice to us to the extent we are subject to certain acquisition transactions pursuant to a tender or exchange offer).

Registration Rights

Under the Transaction Agreement, we also granted Amazon customary registration rights with respect to the Amazon Warrant and the Warrant Shares, including (i) the right to demand registration of the sale of the Amazon Warrant and the Warrant Shares under the Securities Act, (ii) piggyback registration rights to include the Warrant Shares as part of any registration of shares of our common stock under the Securities Act (except for a registration on Forms S-4 or S-8 and certain other limitations set forth in the Transaction Agreement), and (iii) the right to require us to register the Amazon Warrant and the Warrant Shares on a Form S-3 shelf registration statement to allow for the offering of the Amazon Warrant and the Warrant Shares for sale on a continuous basis pursuant to Rule 415 under the Securities Act. Our requirement to register the sale of the Amazon Warrant and the Warrant Shares as provided under clauses (i) through (iii) is, in each case, subject to the terms and conditions set forth in the Transaction Agreement, including our payment of specified fees and expenses related to such registration. The registration rights under the Transaction Agreement will continue until the date on which the Amazon Warrant and all Warrant Shares have been disposed of by Amazon Holdings or any subsidiary of Amazon holding such securities.


Transfer and Standstill Restrictions

The Transaction Agreement also limits Amazon’s ability to transfer the Amazon Warrant to certain unaffiliated third parties and imposes customary standstill limitations on Amazon if, and so long as, Amazon and its subsidiaries beneficially own at least 5% of our outstanding common stock.

Governance Rights

The Transaction Agreement does not provide Amazon with the right to designate any individuals to serve as directors on our Board or, except as described herein, any rights and privileges beyond the rights and privileges associated with the common stock held by our existing stockholders.

Reasons for Requesting Stockholder Approval

Our common stock is listed on Nasdaq, and as a result, we are subject to Nasdaq’s Listing Rules, including Nasdaq Listing Rule 5635(b). Nasdaq Listing Rule 5635(b) requires stockholder approval prior to an issuance of securities that will result in a “change of control” of a listed company, which for Nasdaq purposes is generally deemed to occur when, as a result of an issuance, an investor or a group of investors acquires, or has the right to acquire, 20% or more of the outstanding shares of common stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or voting powerother change in corporate structure effected without the Company’s receipt of consideration, appropriate adjustments will be made to (i) the maximum number of securities issuable under the New ESPP, including the maximum number of securities issuable per participant on any one purchase date and (ii) the number of securities subject to each outstanding purchase right and the purchase price payable per share thereunder.

Amendment and Termination
The New ESPP will terminate upon the earlier to occur of (i) June 30, 2032, or (ii) the date on which all purchase rights are exercised in connection with a Corporate Transaction.
The Plan Administrator may at any time terminate or amend the New ESPP. To the extent necessary to comply with Section 423 of the companyCode (or any successor rule or provision or any other applicable law or listing rule), the Company shall obtain stockholder approval in such a manner and to such ownership or voting power woulda degree as may be the company’s largest ownership position. If the Amazon Warrant vests in full and Amazon Holdings exercises the Amazon Warrant to purchase all of the 53,141,755 Warrant Shares initially subject to the Amazon Warrant, Amazon Holdings would become a holder of approximately 21.0% of the outstanding shares of our common stock (immediately after the issuance of such shares and based onrequired.
New Plan Benefits
Because the number of shares of our common stock outstanding asissued under the New ESPP depends on the level of April 19, 2021). In such event, TMS, a subsidiaryparticipation by its participants, we cannot determine the number of TOTAL and our next largest stockholder, would own approximately 20.1% of our outstanding shares of common stock (that may be awarded in the future to eligible employees.
Federal Income Tax Consequencesexcluding 7,898,021
Following is a general summary of the current federal income tax principles applicable to the New ESPP. The following summary is not intended to be exhaustive and, among other considerations, does not

describe the deferred compensation provisions of Section 409A of the Code to the extent an award is subject to and does not satisfy those rules, nor does it describe state, local or international tax consequences.
The New ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Code. Participant contributions to the New ESPP are made on an after-tax basis. That is, a participant’s New ESPP contributions are deducted from compensation that is taxable to the participant and for which the Company is generally entitled to a tax deduction.
Generally, no taxable income is recognized by a participant with respect to either the grant or exercise of his or her New ESPP option. The Company will have no tax deduction with respect to either of those events. A participant will generally recognize income (or loss) only upon a sale or disposition of any shares of our common stock that are the subjectparticipant acquires under the New ESPP (including upon a deemed sale upon the death of a voting agreement, dated May 9, 2018, among TMS,participant). The particular tax consequences of a sale of shares acquired under the Company and allNew ESPP depend on whether the participant has held the shares for a “Required Holding Period” before selling or disposing of the Company’s then-directorsshares. The Required Holding Period starts on the date that the participant acquires the shares under the New ESPP and officers (the “TMS Voting Agreement”)); however, TMS would also continue to haveends on the right to designatelater of (1) two individuals to serve as directorsyears after the grant date of the offering period in which the participant acquired the shares, or (2) one year after the purchase date on our Board. See “Certain Relationshipswhich the participant acquired the shares.
If the participant holds the shares for the Required Holding Period and Related Party Transactions—Related Party Transactions—Relationships with Total and its Affiliates” for further information. Inthen sells the event we issue additional equity securities inshares at a financing transaction on or prior to October 16, 2021, the number of Warrant Shares subject to the Amazon Warrant will be subject to a Financing Adjustment, which would have the effect of increasing Amazon’s potential ownership of our outstanding shares of common stock. As a result, our issuance of common stock pursuant to the Amazon Warrant, if exercised in full, could cause Amazon Holdings to own 20% or more of our common stock and become our largest stockholder, resulting in a “change of control” for purposes of Nasdaq Listing Rule 5635(b).

Accordingly, we are seeking stockholder approval pursuant to Nasdaq Listing Rule 5635(b) to permit the issuance of Warrant Sharesprice in excess of the Share Cap (which is highest numberpurchase price paid for the shares, the gain on the sale of the shares will be taxed as ordinary income to the participant to the extent of the lesser of (1) the amount by which the fair market value of the shares on the grant date of the offering period in which the participant acquired the shares exceeded the purchase price of the shares, or (2) the gain on the sale of the shares. Any portion of the participant’s gain on the sale of the shares not taxed as ordinary income will be taxed as long-term capital gain. If the participant holds the shares for the Required Holding Period and then sells the shares at a price less than the purchase price paid for the shares, the loss on the sale will be treated as a long-term capital loss to the participant. The Company will not be entitled to a tax deduction with respect to any shares held by the participant for the Required Holding Period, regardless of whether the shares are eventually sold at a gain or a loss.

The participant has a “Disqualifying Disposition” if the participant disposes of the shares before the participant has held the shares for the Required Holding Period. If the participant sells the shares in a Disqualifying Disposition, the participant will realize ordinary income in an amount equal to the difference between the purchase price paid for the shares and the fair market value of the shares on the purchase date on which the participant acquired the shares, and the Company generally will be entitled to a corresponding tax deduction. In addition, if the participant makes a Disqualifying Disposition of the shares at a price in excess of the fair market value of the shares on the purchase date, the participant will realize capital gain in an amount equal to the difference between the selling price of the shares and the fair market value of the shares on the purchase date. Alternatively, if the participant makes a Disqualifying Disposition of the shares at a price less than the fair market value of the shares on the purchase date, the participant will realize a capital loss in an amount equal to the difference between the fair market value of the shares on the purchase ate and the selling price of the shares. The Company will not be entitled to a tax deduction with respect to any capital gain realized by a participant.
Interests in Proposal
All of our common stock can be issued pursuantexecutive officers are eligible to participate in the Amazon Warrant without potentially requiringNew ESPP and thus have a personal interest in the approval of our stockholders pursuant to Rule 5635(b)).

Reasons for the Transactions with Amazon

Our Board determined, in its business judgment, that the transactions with Amazon as described above, including the issuance of the Amazon Warrant, and the possible future purchase by Amazon Holdings of the Warrant Shares issuable thereunder, are in the best interests of the Company and our stockholders. Our Board approved these transactions, subject to any required stockholder approval, and recommends that our stockholders vote in favor of this Proposal 4. In making this determination and approval, the Board considered, among other things, the factors and characteristics of the transactions described below.

New ESPP.

First and most critically, the Board believes Amazon is a valuable strategic partner for Clean Energy. .Under the Fuel Agreement, Amazon will be purchasing low and negative carbon RNG from Clean Energy, initially through 27 existing fueling stations and 19 non-exclusive new or upgraded stations that we expect to construct by the end of the year. The new and existing stations will provide RNG in 15 different states across the United States, and we will own all the stations.


The Warrant Shares vest in multiple tranches, the first of which for 13,283,445 Warrant Shares vested upon execution of the Fuel Agreement. Subsequent tranches will vest over time based on fuel purchases by Amazon and its affiliates, up to a total of $500 million, excluding any payments attributable to “Pass Through Costs,” which consist all costs associated with the delivered cost of gas and applicable taxes determined by reference to the selling price, gallons or gas sold. Importantly, if all the vesting conditions of the Amazon Warrant are satisfied, Amazon will have purchased hundreds of millions of GGEs of RNG at today’s fuel prices from Clean Energy.

We believe a commercial partnership with Amazon will enhance our strategies, initiatives and efforts to achieve our goals to grow fleet and other consumer support for the use of RNG as a vehicle fuel for our target customers and geographies, and other contributions and factors. The Board also believes the proceeds from the issuance of our common stock to Amazon in the event Amazon were to vest and then exercise the Amazon Warrant in part or whole for cash, would enhance our liquidity in support of our operations, as well as our ability to execute our business plans and pursue opportunities for further growth.

Possible Effects if Proposal 4 Is Approved

If this Proposal 4 is approved by our stockholders, then, subject to the satisfaction of the vesting and other conditions set forth in the Amazon Warrant, including as described herein, we would be able to issue to Amazon 2,546,224 shares (the “Additional Warrant Shares”) more than if our stockholders do not approve this proposal, subject to any future anti-dilution and other adjustments. If Amazon were to vest and exercise for cash the entire 53,141,755 shares under the Amazon Warrant, the 2,546,224 of Additional Warrant Shares subject to stockholder approval would represent approximately 1% of our outstanding common stock as of the date of this proxy statement.

The rights and privileges associated with all shares of our common stock issuable under the Amazon Warrant are identical to those associated with our existing common stock, and will not include preemptive, conversion or other rights to subscribe for additional shares of our common stock.

Approval of this Proposal 4, assuming the satisfaction of the vesting and other conditions set forth in the Warrant Agreement and our issuance of the shares issuable thereunder, could have the following effects:

·Dilution. If approved, this Proposal 4 could result in the purchase of the Additional Warrant Shares upon the cash exercise of the Amazon Warrant, in an additional amount of up to 2,546,224 shares, subject to possible future adjustments. As a result, our existing stockholders could own a smaller percentage of our outstanding common stock and, accordingly, a smaller percentage interest in the voting power, liquidation value and book value of our common stock. Moreover, the approval of this Proposal 4 would not limit our ability to engage in additional issuances of our common stock (or securities convertible into or exercisable or exchangeable for our common stock) for capital-raising or other purposes in the future, subject to compliance with Nasdaq Listing Rules and other applicable laws or regulations. As a result, our stockholders could experience further dilution from such additional transactions we may pursue in the future, including as a result of any Financing Adjustment in accordance with the terms of the Amazon Warrant.

·Market Effects. Despite the existence of certain restrictions on transfer, the issuance of the Additional Warrant Shares under the Amazon Warrant could affect trading patterns and adversely affect the market price of our outstanding common stock. Additionally, sales in the public market of the Additional Warrant Shares that could be issued under the Amazon Warrant, or the perception that such sales could occur, could adversely affect the prevailing market price of our common stock and impair our ability to raise capital in future equity financings.

·Concentration of Ownership and Influence. If Amazon Holdings were to both vest and then exercise for cash the Amazon Warrant in full to purchase all of the 53,141,755 Warrant Shares initially subject to the Amazon Warrant, which is subject to possible further adjustment as provided in the Amazon Warrant, it would result in Amazon Holdings owning 21.0% or more of the outstanding shares of our common stock (based on the number of shares of our common stock outstanding as of April 19, 2021). Such ownership would represent the largest ownership position in our Company (if we exclude from TMS’ ownership position the 7,898,021 shares of our common stock that are the subject the TMS Voting Agreements). As a result, Amazon Holdings could be able to exert significant influence over matters requiring approval by our stockholders, including the election of directors and mergers, acquisitions or other extraordinary transactions. Amazon Holdings may have interests that differ from ours or yours, and it may vote or otherwise act in ways with which you disagree and that may be adverse to your interests. In addition, the concentration of ownership in Amazon Holdings may have the effect of delaying, preventing or deterring a change of control of our Company, which could deprive our stockholders of an opportunity to receive a premium for their shares of our common stock as part of a sale of our Company, or conversely, could facilitate a change of control at a time or under circumstances when you and other stockholders may prefer not to sell. Further, the concentration of ownership could adversely affect the prevailing market price for our common stock.


·Valuable Investor and Commercial Partner. As discussed above, we believe Amazon represents a valuable commercial partner and potential investor for us as we continue to pursue increased adoption of RNG as a vehicle fuel among fleet vehicle operators in a variety of markets. Accordingly, we believe securing this commercial partnership and incenting Amazon to purchase the maximum amount of fuel under the Fuel Agreement is important for the trajectory of Clean Energy.

·Improved Capital Levels and Reserves.  The proceeds we would receive upon a future possible cash exercise of the Amazon Warrant could be substantial and would strengthen our balance sheet and increase our capital levels and reserves, and enhance our ability to execute our business plans and pursue opportunities for further growth.

Possible Effects if Proposal 4 Is Not Approved

If this Proposal 4 is not approved by our stockholders, then, pursuant to the Amazon Warrant, the issuance of shares of our common stock exceeding the Share Cap upon exercise of the Amazon Warrant may be restricted by the Nasdaq Listing Rule 5635(b). In such event, however, Amazon would have the right to require us to cause an additional meeting of stockholders to be held every twelve (12) months thereafter until either the Stockholder Approval is obtained or the term of the Amazon Warrant expires. Accordingly, if our stockholders do not approve this Proposal 4, we anticipate that we would seek the Stockholder Approval again at or before our next annual meeting of stockholders and at one or more future meetings of our stockholders thereafter until the Stockholder Approval is obtained or the term of the Amazon Warrant expires.

If we fail to obtain the Stockholder Approval, we would adversely impact the opportunity to obtain the maximum interest of Amazon. Our Board believes the potential value and benefits of our relationship with Amazon then could be materially weakened. As discussed above, we believe our potential transactions with Amazon could prove to be important in the trajectory of Clean Energy, and a failure to obtain the Stockholder Approval could deprive us of some or all of the benefits we anticipate from these potential transactions and relationships.

Securities Law Matters

This Proposal 4, together with the other disclosures contained in this Proxy Statement, is neither an offer to sell nor a solicitation of an offer to buy any of our securities.

The Amazon Warrant and the Warrant Shares have not been registered under the Securities Act or under any state securities law and were offered and issued, as applicable, in reliance upon the exemption from registration requirements of the Securities Act set forth in Section 4(a)(2) of the Securities Act. Clean Energy did not engage in a general solicitation or advertising regarding the issuance of the Amazon Warrant. Amazon has represented to Clean Energy its intention to acquire the Amazon Warrant and Warrant Shares for investment purposes only and not with a view toward their resale, distribution or other disposition in violation of the Securities Act or any applicable state securities laws, and appropriate legends will be affixed to the Amazon Warrant and the Warrant Shares.


No Appraisal Rights

Under applicable Delaware law, our stockholders are not entitled to appraisal rights with respect to the proposed issuance and sale of our common stock to Amazon Holdings upon exercise of the Amazon Warrant.

Required Vote and Effect of Not Casting Your Vote

Proposal 4 must be approved by the affirmative vote of a majority of the votes cast on the proposal by shares of our common stock present or represented by proxy at the Annual Meeting. We expect that Proposal 4 will constitute a “non-routine” matter on which a broker, bank or other nominee is not entitled to vote shares held on behalf of a beneficial owner without receiving voting instructions from the beneficial owner. Consequently, if you hold your shares in street name (such as through a brokerage account) and you do not instruct your broker, bank or other nominee on how to vote on this Proposal 4, a “broker non-vote” will occur with respect to Proposal 4. Abstentions, if any, and broker non-votes with respect to Proposal 4 are not treated as votes cast and will not be counted in determining the outcome of Proposal 4.

OUR BOARD RECOMMENDS A VOTE “FOR” THE APPROVAL OF

THE ISSUANCE OF THE WARRANT SHARES UPON EXERCISENEW ESPP AND THE
RESERVATION OF THE AMAZON WARRANT


PROPOSAL 5

APPROVAL OF AMENDMENT TO OUR RESTATED CERTIFICATE OF INCORPORATION

TO INCREASE THE AUTHORIZED2,500,000 SHARES OF OUR COMMON STOCK

Our Restated Certificate currently authorizes the issuance of 304,000,000 shares of our common stock, par value $0.0001 per share. Our Board is proposing for approval by our stockholders an amendment to our Restated Certificate to increase the number of shares of our common stock we are authorized to issue by approximately 49%, from 304,000,000 shares to 454,000,000 shares. Our Restated Certificate also authorizes the issuance of 1,000,000 shares of preferred stock, par value $0.0001 per share, which would remain unchanged by the amendment to our Restated Certificate contemplated by this Proposal 5.

Background: Current Capitalization

As of April 16, 2021, our capitalization was as follows:

FOR ISSUANCE UNDER THE
NEW ESPP, AS DESCRIBED ABOVE AND SET FORTH IN ANNEX A HERETO.
199,845,902 shares of our common stock were issued and outstanding;

10,886,964 shares of our common stock were issuable upon exercise or vesting and settlement of outstanding options and restricted stock units granted pursuant to our equity incentive plans;

53,141,755 shares of our common stock were issuable upon exercise of the Amazon Warrant if Proposal 4 is approved, subject to additional anti-dilution adjustments as described in Proposal 4 (if Proposal 4 is not approved, 50,595,531 shares of our common stock would be issuable upon exercise of the Amazon Warrant);

17,352,835 shares of our common stock were reserved for issuance pursuant to our employee stock purchase plan or pursuant to equity awards we may grant in the future under our equity incentive plans; and

No shares of our preferred stock were issued or outstanding. There are currently no plans, arrangements, commitments or understandings to issue any shares of our preferred stock.

Based on the above capitalization information, only 22,772,544 shares of our currently authorized common stock remained unissued and unreserved and available for future issuance as of April 16, 2021.

Reasons for the Increase to Our Authorized Shares of Common Stock

The Board has determined, in its business judgment, that an increase to our authorized shares of common stock by approximately 49%, from 304,000,000 shares to 454,000,000 shares, is in the best interests of the Company and our stockholders, and as a result the Board has unanimously approved such an increase, subject to stockholder approval, and has unanimously recommended that our stockholders approve such an increase by voting in favor of this Proposal 5. In making this determination and approval, the Board considered, among other things: the potential issuance of shares of our common stock upon exercise of the Amazon Warrant as described in Proposal 4 above; our historical share issuance rates, as described below; anticipated future share requirements; guidelines and potential voting recommendations of third-party proxy advisory services, including Institutional Shareholder Services; recent practices at other public companies; and a recommendation from our management.

The Board is requesting that our stockholders approve the increase to the authorized shares of our common stock in part to enable us to provide meaningful capital resources for our business plans and strategic initiatives.

The Board is also requesting that our stockholders approve the increase to the authorized shares of our common stock to provide us with the flexibility to issue our common stock as needed for other purposes. The newly authorized shares of our common stock would be issuable for any proper corporate purpose. Historically, we have issued our common stock (or securities convertible into or exercisable or exchangeable for our common stock) for the following main reasons:

as consideration for mergers, acquisitions, investments or other similar transactions;


in connection with establishing collaborations or other strategic relationships;

as compensation to attract and retain our personnel through grants of equity awards; and

in capital-raising or financing transactions.

Since January 2019, we have issued common stock (or securities convertible into or exercisable or exchangeable for common stock) totaling 58,206,062 shares (on a fully diluted basis) for the reasons described above, and our Board may desire to use our common stock for these or other reasons in the future. Of these shares, since January 2019, we have issued shares of our common stock or granted equity awards in respect of shares of our common stock under our equity incentive plans for a total of 7,610,531 shares (on a fully diluted basis), and the Board believes the availability of additional shares for future compensatory purposes is an important recruiting and retention tool.

Except with respect to the issuance of shares of our common stock upon exercise of the Amazon Warrant (which we are asking our stockholders to approve in Proposal 4 and the issuance of shares of our common stock in connection with our employee stock purchase plan and equity compensation plans and awards granted thereunder, we currently have no specific understandings or commitments, oral or written, that would require us to issue a material amount of new shares of our common stock. In 2021, we anticipate deploying up to approximately $100.0 million to develop dairy RNG production projects and $45 million to $60 million to build fueling stations that will support RNG volume contracted to Amazon. If we deploy the foregoing capital, we will be required to raise significant additional capital during 2021, which may involve the issuance of a material amount of new shares of our common stock.21

Possible Effects if Proposal 5 Is Approved

If this Proposal 5 is approved by our stockholders, the Board would generally be able to issue the additional authorized shares in its discretion from time to time without further action by or approval of our stockholders, subject to and as limited by the rules and listing requirements of Nasdaq or any other then applicable securities exchange and the requirements of all applicable law, and subject to our commitment to issue and sell shares of our common stock upon exercise of the Amazon Warrant.

Approval of this Proposal 5 could have the following effects:

Potential for Dilution. If approved, this Proposal 5 would result in our Board’s ability to issue the newly authorized shares of our common stock in the future, in its discretion and without obtaining future stockholder approval. Because our stockholders do not have preemptive rights with respect to our common stock, they would not have preferential rights to purchase any additional shares we may issue in the future. Consequently, any issuance of additional shares of our common stock, unless such issuance is pro-rata among existing stockholders, would increase the number of outstanding shares of our common stock and decrease the ownership interest of our existing stockholders, as well as their percentage interest in the voting power, liquidation value and book value of our common stock. Depending on the terms of any such issuance, these decreases could be significant. It is impossible to predict the dilutive impact of any such future share issuance, if any. Any potential dilution would depend on several factors, including the price of our common stock at the time of any future issuance and the number of shares of our common stock then outstanding.

Anti-Takeover Effects. The availability of additional shares of our common stock for issuance could, under certain circumstances, discourage or make more difficult efforts to effect a change of control of our Company or remove current management, which our stockholders might otherwise deem favorable. For example, without further stockholder approval, the Board could strategically sell shares of our common stock in a private transaction to purchasers that would oppose a change of control attempt or favor current management. The anti-takeover effect of an increase to the authorized shares of our common stock would be in addition to other provisions in our Restated Certificate and our amended and restated bylaws that may also have an anti-takeover effect, such as certain advance notice requirements with respect to any stockholder proposals and nominations of director candidates, the lack of cumulative voting rights of our stockholders, and our ability to issue preferred stock with such rights, preferences and privileges as approved by our Board without obtaining stockholder approval. The Board is not aware of any attempt, or contemplated attempt, to acquire the Company, nor is this Proposal 5 being presented with the design or intent that it be used to prevent or discourage a change of control or management or an acquisition attempt.


However, stockholders should be aware that nothing would prevent the Board from taking any such actions that it deems consistent with its fiduciary duties.

Possible Effects if Proposal 5 Is Not Approved

If this Proposal 5 is not approved by our stockholders, then the number of shares of our common stock we would be authorized to issue would remain at its current amount of 304,000,000 shares.

A failure to obtain the approval of our stockholders of this Proposal 5 could result in a lack of necessary flexibility to use equity for valid purposes. As described above, the Board believes this increase to the authorized shares of our common stock would provide us with needed flexibility to issue these shares in the future when and as necessary and on a timely basis, which would allow us to take advantage of market conditions, the availability of favorable financing and opportunities for acquisitions, in each case without the potential expense or delay incident to obtaining stockholder approval for each separate transaction or issuance. If this Proposal 5 is not approved by our stockholders, our Board would have significantly limited ability to issue equity at its discretion in the future, which could result in, among other things, difficulties retaining and recruiting executives and other personnel consistent with our business plans or an inability to effect potential future strategic or capital-raising transactions or acquisitions efficiently and when desired or otherwise believed to be advantageous to us.

Rights of Additional Authorized Shares of Common Stock

Any authorized shares of our common stock, when issued, would be part of our existing class of common stock and would have the same rights and privileges as the shares of common stock that are presently issued and outstanding.

Text and Effectiveness of the Increase to Our Authorized Shares of Common Stock

We propose to affect the increase to the authorized shares of our common stock by amending the first two sentences of Article 4.A of our Restated Certificate of Incorporation to read in their entirety as follows:

“This corporation is authorized to issue two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock.” The total number of shares of stock which this corporation is authorized to issue is 454,000,000 shares, 453,000,000 of which shall be Common Stock with a par value of $.0001 per share, and 1,000,000 of which shall be Preferred Stock with a par value of $.0001 per share.”

The only change to the language of Article 4.A being voted on in this Proposal 4 is to increase the total number of shares of our common stock we may issue by approximately 49%, from 304,000,000 shares to 454,000,000 shares, and consequently the total number of shares of stock we may issue by the same amount. Other than as set forth above, our Restated Certificate as currently in effect would remain unchanged by the amendment to affect the authorized share increase contemplated by this Proposal 5.

If this Proposal 5 is approved and adopted by our stockholders at the Annual Meeting, the increase to our authorized shares contemplated hereby would become effective upon our filing of a Certificate of Amendment to our Restated Certificate with the Secretary of State of the State of Delaware reflecting the amendments to Article 4.A thereof as set forth above, or at such other date and time as may be specified in the Certificate of Amendment. We expect to file such an amendment with the Secretary of State of the State of Delaware as soon as practicable following stockholder approval.

No Appraisal Rights

Under applicable Delaware law, our stockholders are not entitled to appraisal rights with respect to the proposed amendment to our Restated Certificate to increase the number of authorized shares of common stock we are authorized to issue.

Required Vote and Effect of Not Casting Your Vote

Proposal 5 must be approved by the affirmative vote of the holders of a majority of the issued and outstanding shares of our common stock entitled to vote on the proposal at the Annual Meeting. We expect that Proposal 5 will constitute a “routine” matter on which a broker, bank or other nominee is entitled to vote shares held for a beneficial owner even without receiving voting instructions from the beneficial owner. As a result, abstentions, if any, will have the same effect as a vote against this Proposal 5, and broker non-votes are not expected to occur on Proposal 5.

Board Committees

We have established the following active committees: an audit committee, compensation committee, and nominating and corporate governance committee. Our Board also creates committees from time to time to oversee financing transactions or other significant corporate matters. Our Board and audit committee generally meet at least quarterly, and our other committees meet on an as-needed basis. Each of the Board committees has the responsibilities described below. Copies of the current charters of the audit committee, compensation committee, and nominating and corporate governance committee, as adopted by the Board, are accessible on our website at http://investors.cleanenergyfuels.com/corporate-governance.

Audit Committee

We believe the functioning of our audit committee complies with all applicable requirements of the Sarbanes-Oxley Act of 2002 and with all applicable Nasdaq and SEC rules. The functions of this committee include:

Reviewing, overseeing and approving all related-party transactions (as such term is defined in applicable SEC rules).


Compensation Committee

We believe the functioning of our compensation committee complies with all applicable Nasdaq and SEC rules. The functions of this committee include:

Reviewing and approving all of our compensation plans, policies and programs as they affect our executive officers;

·
Administering our equity incentive plans and employee stock purchase plans;

The compensation committee may designate one or more subcommittees, each subcommittee to consist of two or more members of the compensation committee and may generally delegate its authority to any such subcommittee(s).

Nominating and Corporate Governance Committee

We believe the functioning of our nominating and corporate governance committee complies with all applicable Nasdaq and SEC rules. The functions of this committee include:

·
Developing and recommending to the Board criteria to be used in screening and evaluating potential director candidates;

·
Reviewing, evaluating and recommending to the Board qualified director candidates;

·
Monitoring and reviewing any issues regarding director independence or involving potential conflicts of interest; and

Developing and recommending to the Board corporate governance guidelines and a code of ethics and reviewing and recommending changes to these documents as appropriate.

Board Leadership Structure

The Board has determined that our current structure of separating the roles of Chairman of the Board and Chief Executive Officer is in the best interests of the Company and our stockholders. Mr. Scully has served as Chairman of the Board since January 2018; and Mr. Littlefair has been the Chief Executive Officer of the Company since June 2001. As Chairman of the Board, Mr. Scully focuses on organizing Board activities to enable the Board to effectively provide guidance to and oversight (including risk oversight) and accountability of management. The Chairman of the Board, among other things, creates and maintains an effective working relationship with the Chief Executive Officer and other members of management and with the other members of the Board, provides the Chief Executive Officer ongoing direction regarding Board needs, interests and opinions, and ensures the Board agenda is appropriately directed toward matters significant to the Company. Separating the roles of Chairman of the Board and Chief Executive Officer allows Mr. Littlefair, as Chief Executive Officer, to focus on managing the day-to-day direction and implementing the long-term strategic goals of the Company.


The functions of the Board are carried out by the full Board and, when delegated, by the Board’s committees. Each director is a full and equal participant in the major strategic and policy decisions of our Company.

Board Role in Risk Oversight

Risk is inherent in every business. We face a number of risks, including business, operational, strategic, competitive, financial, political, legislative, environmental, safety and regulatory risks, as well as risks related to compensation, cybersecurity threats or incidents, capital expenditures, derivative transactions, commodity-based exposures, acquisitions or other strategic transactions and financing and other liquidity matters. In general, our management is responsible for the day-to-day management of the risks we face, while our Board, as a whole and through its committees, is responsible for the oversight of risk management.

In its risk oversight role, the Board and each of its committees regularly review and discuss, internally and with management, the material risks confronting our business, based on reports prepared and delivered by management that address these risks and other information deemed relevant. The Board also monitors our risk management and corporate governance policies, including the day-to-day risk management processes designed and implemented by management, and generally evaluates how management operates our Company with respect to risk exposures. These risks and risk management policies are also reviewed and

24


analyzed in depth by the Board at an annual strategic planning session with members of senior management. The Board considers the risks and vulnerabilities we face when granting authority to management and approving business strategies and particular transactions. Additionally, the full Board oversees our initiatives and risk management activities relating to sustainability, diversity, equity and inclusion.

The Board performs its risk oversight function in part through its committees, which are comprised solely of independent directors. Each Board committee’s risk oversight role is as follows:

·
The audit committee oversees management of risks related to our financial reporting, disclosure processes and accounting policies, and information technology and cybersecurity, as well as any related party or conflict-of-interest transactions;

·
The compensation committee oversees management of risks related to our compensation practices and policies; and

·
The nominating and corporate governance committee oversees management of risks related to Board processes and composition, including director independence, and corporate governance matters.

Information Security

Our Chief Operating Officer oversees cybersecurity and other information technology risks affecting the Company and reports on the same to the Board at least quarterly. Our Audit Committee formally oversees information security, including cybersecurity risks, and receives regular updates from management. We use a combination of internal security technology solutions, paired with strategic external partnerships to mitigate cybersecurity threats to the Company. We leverage the cybersecurity framework of our security managed service provider and anticipatehave implemented a rollout of a formaltraining and compliance cybersecurity program this calendar year.program. We have, and will continue to, use third party security firms to perform simulated cyber-attacks on our environment to identify exploitable vulnerabilities. We use these results to harden our security posture with our security managed service provider. Our information technology infrastructure is externally audited as part of our Sarbanes Oxley audit process and our controls include information security standards. We maintain standalone cybersecurity insurance and believe we are adequately insured against losses related to a potential information security breach. We have not experienced a material breach in information security.


Code of Ethics

We have adopted a written code of ethics applicable to our directors, officers and other employees, including our principal executive, financial and accounting officers and controller or persons performing similar functions. This code of ethics establishes policies to promote honest and ethical conduct and is designed to comply with applicable Nasdaq and SEC rules. The nominating and corporate governance committee reviews our code of ethics periodically and may propose or adopt additions or amendments that it determines are required or appropriate.

Our code of ethics is accessible on our website at
http://investors.cleanenergyfuels.com/corporate-governance
. We expect that any amendments to or waivers from certain provisions of our code of ethics applicable to any principal executive, financial or accounting officer or controller or persons performing similar functions will be disclosed on our website to the extent required by applicable Nasdaq or SEC rules.

Corporate Governance Guidelines

We have adopted written corporate governance guidelines that set forth standards for director qualifications and responsibilities, Board committees, Board leadership structure, director compensation, Chief Executive Officer evaluation and management succession, Board self-evaluations, Board oversight of the Company’s strategic planning, and director and officer stock ownership, among other things. The nominating and corporate governance committee reviews our corporate governance guidelines periodically and may from time to time propose or adopt additions or amendments it determines are required or appropriate. Our corporate governance guidelines are accessible on our website at http://investors.cleanenergyfuels.com/corporate-governance.

Board EvaluationsEvaluations

At least annually, our nominating and corporate governance committee leads an evaluation of each of our directors and our Board as a whole and each of its committees. As part of this evaluation, the Board considers the areas in which the Board believes it could improve.

Chief Executive Officer Evaluation and Management Succession

Our Board works with our nominating and corporate governance committee to evaluate potential successors to our Chief Executive Officer and to ensure that a CEO succession plan is in place. Our Chief Executive Officer also makes available his recommendations and evaluations of potential successors, as well as reviews any development plans recommended for such individuals.

Director Stock Ownership Guidelines

We believe it is important to encourage our directors to hold a material amount of our common stock, which links their long-term economic interest directly to that of our stockholders. To achieve this goal, we have established stock ownership guidelines applicable to our directors. These guidelines provide that each non-employee director is required to own shares of our common stock valued at $180,000 or more by the later of December 14, 2019 and five years after the date of a directorsdirector’s initial election to the Board. Stock options are not counted toward satisfaction of these stock ownership requirements. Directors who attain this stock ownership level by the stated deadline will continue to satisfy the stock ownership requirements if the value of their stock holdings declines after such deadline solely due to a decrease in the trading price of our common stock. All of our non-employee directors, with the exception of Messrs. CharleuxMses. Boissy-Rousseau and Maurisse, who are not subject to the policy as described below,Paskett and Mr. Wolffsheim, had satisfied these stock ownership guidelines as of the record date for the Annual Meeting. TheMs. Paskett, who was appointed to the Board in December 2021, is still within the five-year grace period to comply with the stock ownership guidelines. In addition, the Board has determined that the director stock ownership guidelines do not apply to Mr. CharleuxMs. Boissy-Rousseau or Mr. MaurisseWolffsheim for so long as each is designated by TMS to serve as a director and waives his or her right to receive compensation for serving on the Board. See the descriptions under “Proposal 1: Election of Directors—Directors — General” and “Director Compensation” for more information.

We have also established stock ownership guidelines applicable to certain of our executive officers, which are described under “Compensation Disclosure and Analysis—Analysis — Executive Stock Ownership Guidelines” below.


Stockholder Communications with the Board

We have adopted a formal process by which stockholders and interested parties may communicate with our Board, which is accessible on our website at
http://investors.cleanenergyfuels.com/corporate-governance/contact-the-board
. This centralized process assists the Board in reviewing and responding to communications from stockholders and other interested parties in an appropriate manner. Communications to the Board must be in writing and mailed to our Corporate Secretary at the address of our principal executive offices. The communication can be addressed to one or more individual directors or to the Board as a group, and the name of any specific intended recipient(s) should be noted in the communication. Communications submitted by postal mail may be anonymous. The Corporate Secretary typically reviews all such communications and will forward them to the Board or any identified individual director(s), unless any such communication is deemed to be, in the Corporate Secretary’s discretion, unrelated to the duties and responsibilities of the Board or unduly hostile, threatening, illegal or similarly unsuitable for Board consideration.

Director Nomination Process

Our Board, as a whole and through our nominating and corporate governance committee, is responsible for identifying, evaluating and recommending nominees to serve as directors of our Company.

Identifying and Evaluating Director Nominees

Our nominating and corporate governance committee is responsible for identifying individuals qualified to become members of the Board and recommending these candidates to our Board for nomination

TABLE OF CONTENTS

or appointment. Our nominating and corporate governance committee may utilize a variety of methods to identify potential director candidates. For example, candidates may come to the attention of the nominating and corporate governance committee through current members of the Board, executive officers, professional search firms, stockholders or others. These candidates may be evaluated and considered by our nominating and corporate governance committee at any point during the year, including in connection with each annual meeting of our stockholders. For each such annual meeting, the nominating and corporate governance committee recommends to our Board certain director nominees to stand for election at the annual meeting based on the committee’s evaluation of all potential director candidates, including incumbent directors. The Board then selects its director nominees based on its determination, relying on the recommendation of and other information provided by the nominating and corporate governance committee as it deems appropriate, of the suitability of each potential director candidate to serve as a director of our Company.

Stockholder Recommendations of Director Candidates

In accordance with its charter, our nominating and corporate governance committee is responsible for considering and evaluating properly submitted stockholder recommendations of candidates for Board membership. Any such recommendation of director candidates for nomination by the Board in connection with our next annual meeting of stockholders should be made in writing by January 1st of the applicable year and delivered or mailed to our Corporate Secretary at the address of our principal executive offices, and should include the name, address and a current resume of the proposed director candidate, a statement describing the candidate’s qualifications and consent to serve on our Board if selected as a director nominee, and contact information for personal and professional references. The submission should also include the name and address of the stockholder who is submitting the proposed director candidate, the number of shares of our common stock that are owned of record or beneficially by the submitting stockholder and a description of all arrangements or understandings between the submitting stockholder and the proposed director candidate. We may also request that any proposed director candidate and any stockholder proposing a director candidate furnish us with such other information as may reasonably be required for our nominating and corporate governance committee to determine the eligibility of such proposed director candidate to serve as a director of our Company.

All properly submitted stockholder recommendations will be aggregated together and with any other director candidates proposed by other sources, for consideration and evaluation by our nominating and corporate governance committee and will receive the same consideration by our nominating and corporate governance committee as is received by any other director candidate. In evaluating all director candidates, the nominating and corporate governance committee will consider, among other things, the director qualifications set forth in our corporate governance guidelines, as described in “Proposal 1: Election of Directors” above. Any stockholder-recommended director candidate that is selected by our nominating and corporate governance committee would be recommended by the committee as a director nominee to the Board, which would then consider and evaluate the candidate in the same manner and based on the same criteria and qualifications as other prospective director candidates. If approved by the Board, the stockholder-recommended candidate would be appointed as a director to a vacant seat on the Board or included in the Board’s slate of director nominees to stand for election at our next annual meeting of stockholders.

Sustainability Strategy

Our vision is to deliver renewable transportation fuel for a cleaner, safer, more equitable tomorrow.   We are launching a bold program, supported by ambitiouslaunched our strategy and goals to drive progress across three pillars: fueling the transition to renewable energy in transportation, building the workforce for the future of renewable energy, and advancing smart policies that drive the transformation to zero carbonrenewable fuels.

In 2021, we continued to focus on building trusted partnerships with our stakeholders to help achieve progress towards our goals, as well as on improving our operations to align with our sustainability goals. We recognize that our environmental impact includes more than our products and that we must foster a culture of sustainability in our operations. Each of the three pillars of our sustainability strategy incorporates parts of our own business operations, to ensure that our advocacy and external progress in sustainability is aligned with our internal operations.

COMPENSATION DISCUSSION AND ANALYSIS

Overview

This compensation discussion and analysis describes the material features of the compensation awarded to, earned by, or paid to each person who served as our principal executive officer (Andrew J. Littlefair) or principal financial officer (Robert M. Vreeland) in 2020,2021, and the only two other individuals who were serving as executive officers at the end of 20202021 or at any time during the 2021 calendar year (Mitchell W. Pratt and Barclay F. Corbus). Messrs. Littlefair, Vreeland, Pratt and Corbus are collectively referred to as our “named executive officers.” This analysis also discusses our compensation philosophy and objectives, the methodologies used for establishing the compensation programs for the named executive officers, and the policies and practices for administering such programs.

Business

We are North America’s leading provider of the cleanest fuel for the transportation market, based on the number of stations operated and the amount of GGEsgasoline gallon equivalents (“GGEs”) of renewable natural gas (“RNG”)RNG and conventional natural gas delivered. Through our sales of RNG, which is derived from biogenic methane produced by the breakdown of organic waste, we help thousands of vehicles, from airport shuttles to city buses to waste and heavy-duty trucks, to reduce their amount of climate-harming greenhouse gas, from 60% and to over 400% based on California Air Resources Board determinations, depending on the source of the RNG, while also reducing criteria pollutants such as Oxides of Nitrogen, or NOx. RNG is delivered as CNGcompressed natural gas (“CNG”) and LNG.liquefied natural gas (“LNG”). Our sales of RNG have increased dramatically, from 13.0 million GGEs in 2013 (the year we introduced our RNG to the vehicle fuel market) to 153.3167.0 million GGEs in 2020. With the2021. The Company’s focus on RNG, our sales of RNG have grown from 12% of our vehicle fuel sales in 2013 to 74%78% of our vehicle fuel sales in 2020.2021. We believe that during 20202021 we provided 61%58% and 45%47% of the RNG used for transportation fuel in California and the United States, respectively. We are in a unique position becauseOur business uniquely benefits from the valuable U.S. federal, state and local government credits generated by selling RNG as a vehicle fuel (collectively, “Environmental Credits”), which are generated by the party that dispenses RNG into vehicle fuel tanks, and wetanks. We believe we have access to more dispensers than any other market participant.

As a clean energy solutions provider, we supply RNG and conventional natural gas, in the form of CNG and LNG, for heavy and medium-duty vehicles; design and build, as well as operate and maintain, public and private fueling stations; sell and service compressors and other equipment used in RNG production and at fueling stations; transport and sell RNG and conventional natural gas via “virtual” natural gas pipelines and interconnects; sell Environmental Credits we generate; and obtain other federal, state and local tax credits, grants and incentives.

We serve fleet vehicle operators in a variety of markets, including heavy-duty trucking, airports, refuse and public transit. We believe these fleet markets will continue to present a growth opportunity for our vehicle fuels for the foreseeable future. As of December 31, 2020,2021, we serve over 1,000 fleet customers operating over 48,000 vehicles, anddeliver RNG to the transportation market through 548 fueling stations we own, operate or supply 565 fueling stations in 3942 states and the District of Columbia in the United States and five provincesU.S., including over 200 stations in Canada.

Impact of COVID-19

California

The COVID-19 pandemic has resulted, and is likely to continue to result, in significant economic disruption and has adversely affected and will likely continue to adversely affect our business. Our operations have been designated “essential critical infrastructure work” in the energy sector by the U.S. Department of Homeland Security, meaning that we have been able to continue operating to the fullest extent possible. While continuing our business operations, we are focused on protecting the health and wellbeing of our employees, customers, and the communities in which we operate. All our vehicle fueling stations have remained fully operational during the COVID-19 pandemic and continue to provide access to customers--many that are supplying essential services.

We have adopted and applied protocols and procedures in accordance with federal, state, and local government policies and mandates and Centers for Disease Control guidelines for our offices. Specifically, we have implemented enhanced cleaning and disinfecting protocols and procedures like temperature and COVID-19 screening questionnaires for the health and safety of our employees, customers, and the communities in which we operate. We have provided personal protective equipment (including masks and gloves) and hand sanitizer, we have modified office seating, we expect all our employees to maintain appropriate physical distancing, and we continue to restrict employee travel in accordance with the various state health orders. 


We began to see the negative effects of COVID-19 on volumes delivered in mid-March 2020 and continued to see declines in volumes delivered through December 31, 2020, as compared to 2019. Our volumes bottomed in the second quarter of 2020 and improved through year-end albeit at a slower pace than expected, with volumes delivered for the fourth quarter of 2020 increasing 7% over the second quarter of 2020. While volumes delivered in December 2020 were 2% lower compared to December 2019, this decline was lower than the decline of 4% when comparing September 2020 to September 2019. The most significant negative effects of COVID-19 in relation to our volumes were experienced in the airports (fleet services) and public transit customer markets, which were down by between 15% and 31% during 2020 compared to 2019 due to federal, state and local government mandates to restrict normal daily activities, as well as travel bans, quarantines and “shelter-in-place” orders. The refuse and trucking markets grew in 2020 compared to 2019, due to strong demand.

Our volume of GGEs delivered for the year ended December 31, 2020 declined 5% compared to the prior year. It is possible that the prolonged effect of the COVID-19 pandemic could negatively affect our future volumes. Declines in volume have resulted and could continue to result in lower gross margin dollars year-over-year and likely a lower gross margin per GGE due to lower output on fixed operating costs and the effect of less revenue from Environmental Credits. Lower volumes have affected and may continue to affect our alternative fuels tax credit (“AFTC”) revenue as a portion of the decline in volume is from AFTC-eligible volumes. In 2020 we had lower operating expenses, which helped mitigate the lower gross profit margins from lower volumes.

Key 2020-20212021-2022 Pay Decisions

Key pay decisions for 20202021 and 2021 to date2022 include the following:

·For 2020 the compensation committee maintained the base salaries for our named executive officers at their 2019 levels.

·The compensation committee awarded cash incentives under our 2020 performance-based cash incentive plan to our named executive officers below each executive’s target incentive.

·The compensation committee awarded additional special discretionary cash incentives to our named executive officers for performance in 2020.

·In the first quarters

For 2021 the compensation committee maintained Mr. Littlefair’s base salary at his 2020 level (it has been at the same level since 2015) and increased the base salaries of Messrs. Vreeland, Pratt and Corbus by 13%, 8% and 8%, respectively.

Based on our performance results achieved for 2021, the compensation committee awarded cash incentives under our 2021 performance-based cash incentive plan to our named executive officers above each executive’s target incentive.

In the first quarter of 2020 and 2021, the compensation committee granted RSUs and stock options to our named executive officers, in accordance with our regular grants of long-term incentives to employees.

In December of 2021, the compensation committee introduced two new types of performance-based stock option awards that were granted to the named executive officers as additional long-term

incentives. The first new performance-based option is structured to incentivize securing additional GGEs of RNG supply via investment to increase the volume of our RNG deliveries, and the vesting of 100% of each grant is subject to the Company’s attainment of RNG supply milestones. The second new performance-based option is structured to incentivize long-term appreciation in the value of our shares, and the vesting of 100% of each grant is subject to the Company’s attainment of a stock price representing a greater than 100% premium above the closing price of a share of common stock on the grant date. The compensation committee determined in December that the Company was at a critical juncture and that it was of primary importance to incentivize the named executive officers to (1) create long-term stockholder value by increasing the Company’s price per share and (2) strategically execute on expanding our RNG business over the long-term. The December grants represent the largest component of each named executive officer’s 2021 compensation and are intended to provide a meaningful performance-based equity incentive over a number of years going forward. Because of the December grants, the compensation committee determined it will not grant any additional equity awards to named executive officers in calendar 2022.

No additional equity awards will be made to named executive officers in accordance with our regular grants of long-term incentives to employees.calendar 2022.

·For 2021 the compensation committee maintained Mr. Littlefair’s base salary at his 2020 level (it has been at the same level since 2015) and increased the base salaries of Messrs. Vreeland, Pratt and Corbus by 13%, 8% and 8%, respectively.

Compensation Program Objectives and Philosophy

Our compensation committee oversees the design and administration of our executive compensation program. The primary objectives of our executive officer compensation program are to attract, retain and motivate talented and dedicated executive officers; to reward individual performance and achievement of key corporate objectives, including the objectives set forth in our annual strategic plan, without promoting excessive or unnecessary risk-taking; to align the interests of our executives with those of our stockholders; and to provide compensation that we believe is fair in light of an executive’s experience, responsibilities, performance and tenure with our Company and in relation to the compensation provided to other executives of our Company and comparable executives at certain peer companies.


To achieve these objectives, we maintain an executive compensation program that includes the following components: base salary, cash incentives, equity incentives, change in control and post-termination severance compensation and other benefits. The compensation committee developed our executive compensation program by drawing on its experience and judgment in establishing programs it believes are appropriately rewarding and responsible for a growth company in a developing industry. The compensation committee reviews and evaluates our executive compensation program, including its objectives and the forms of compensation used to achieve these objectives, on at least an annual basis, and adjusts the program as it deems appropriate and considers factors relevant in establishing appropriate levels and mix of compensation for our executives.

Process for Determining Executive Compensation

The compensation committee’s general practice is to establish the annual compensation mix and levels for each of our executives inat the beginning of each fiscal year, typically in our first quarter in connection with annual performance reviews. Performing this process after the end of the prior year allows the compensation committee to incorporate into its analysis information on the Company’s and each individual’s performance during the prior year and to assess each executive’s overall contributions to the Company. The compensation committee then compiles this information to establish annual base compensation and performance-related targets and to adjust long-term incentives as appropriate.

However, as discussed above and below, the compensation committee spent significant time in the third and fourth quarter of 2021 evaluating the structure of our long-term equity incentive awards, and in connection with the introduction of two new types of performance-based options, determined to grant the named executive officers their long-term incentive award in December of 2021. Because of the December grants, the compensation committee determined it will not grant any additional equity awards to named executive officers in calendar 2022.

Compensation Consultant

Our compensation committee has the authority to engage the services of compensation consultants or other experts or advisors as it deems appropriate in fulfilling its responsibilities. In 2012,responsibilities and has retained the compensation committee engagedservices of Semler Brossy Consulting Group, LLC (“Semler Brossy”) to assist the committee in performing its responsibilities.. The compensation committee has the sole authority to approve the terms of this engagement, and Semler Brossy reports solely to the compensation committee only under this engagement. Before engaging Semler Brossy, the compensation committee determined that Semler Brossy was independent and that its work would not raise any conflicts of interest after taking into consideration the factors set forth in applicable Nasdaq and SEC rules.

Compensation Consultant’s 20172021 Review

In the third quarter of 2016,2021, the compensation committee instructed Semler Brossy to complete a full review of the Company’s executive and director compensation programsprogram within the context of the competitive market, including comparing the Company’s executive and director compensation components and levels with a group of selected peer companies and general industry survey data regarding executive compensation practices at companies with a similar market capitalization as our Company at the time of the review. Although thethat is described in more detail below. The compensation committee primarily utilized and relied upon the review and other information provided byconsulted with Semler Brossy in connection with its 2017 compensation decisions, the compensation committee also referenced someintroduction of the information provided by Semler Brossytwo new types of performance-based options granted in making certain 2020 compensation decisions.

We expect that the compensation committee will engage Semler Brossy inDecember, 2021 to complete another review of the Company’s executivefor 2022 and director compensation programs.

beyond.

Peer Group

Selecting a group of our peer companies is challenging for many reasons, including principally our belief that we are the only publicly traded company, whosethe primary line of business of which is to sell RNG, CNG and LNG for use as a vehicle fuel. In selecting our peer companies for compensation purposes, our compensation committee generally sought to identify companies that are similar to us across a number of metrics and that, in the compensation committee’s view, compete with us for talent. As a result, with the assistance of Semler Brossy and with input from management, our compensation committee developed a group of peer companies in the third quarter of 2016 consisting of stand-alone, publicly traded companies that were of a similar size as us, based on revenue and market capitalization at the time the peer group was developed; have complex structures; and operate in our industry or in another heavily regulated energy or non-mature industry.
In 2017,2021, the compensation committee selectedworked with Semler Brossy to review our peer group given our strategic shift to producing RNG in addition to our downstream distribution of natural gas.
Based on Semler Brossy’s recommendations, the compensation committee approved the following 23 companies as our peer companies for compensation purposes, which we refer to collectively as the “Peer Group,Group. and the Peer Group has been modified since 2017 to remove companies that are no longer subject to the requirements of the Exchange Act and to reflect changes to names because of business combinations or acquisitions.

As of June 15, 2021 to date, the compensation committee did not tie named executive officer compensation (either specific elements of compensation or total compensation levels) to any predetermined benchmark but did continue to usewhen the Peer Group data as onewas initially constructed, our 200-day average market capitalization was at the 57th percentile of many reference points when setting executive officer compensation levels through the exercisePeer Group companies, while our trailing twelve-month revenues and EBIT were at the 37th percentile and 51st percentile of its business judgment.

The compensation committee believes benchmarking may not always be the most appropriate tool for setting compensation due to aspects of our business, objectives, and the way we’ve structured executive roles that may be unique to us. As a result, the compensation committee retains discretion to vary executive compensation components and levels from targeted marketlevels.

when setting executive officer compensation levels through the exercise of its business judgment.

Review of Stockholder Say-on-Pay Votes

Consistent with the preference of our stockholders, which was expressed at our annual meeting of stockholders held in May 2018, our stockholders can cast an advisory vote on executive compensation, or a “say-on-pay” vote, once every year, and the next such vote will occur at the Annual Meeting. At the Company’s annual meeting of stockholders held in 2020,2021, our executive compensation received a favorable advisory vote from approximately 95.09%95% of the votes cast on the proposal at the meeting (which excludes abstentions and broker non-votes).

We believe the high degree of support on our 2021 say-on-pay proposal, together with a similar high degree of support on our 2020 say-on-pay proposal, demonstrates that stockholders support our executive compensation program design.

We expect to actively engage with our stockholders to discuss various compensation and governance matters and consider their feedback in determining named executive officer compensation. The compensation committee will also continue to consider the outcome of the Company’s say-on-pay votes, as well as this direct stockholder input, when making future compensation decisions for our named executive officers and in respect of our compensation program generally.

Components of Compensation

Our named executive officers’ compensation consists of the following components:

·Base salary;

·Performance-based and discretionary cash incentives;

·Equity incentives;

·Change in control and post-termination severance compensation; and

·Other benefits that are generally available to all of our salaried employees.

[MISSING IMAGE: tm223596d1-pc_compen4c.jpg]
The compensation committee views the various components of compensation as distinct methods of achieving the various objectives of our compensation program and, as a result, it generally does not believe significant compensation derived from one component should negate or reduce compensation from other components. The compensation committee does, however, review and evaluate each executive’s total compensation, and it may make decisions regarding levels of certain compensation components based on this evaluation of overall compensation, including, for instance, determinations regarding target levels under our performance-based cash incentive plan or determinations regarding discretionary cash incentives.plan. The compensation committee also strives to provide an appropriate mix of long-term and short-term, cash and non-cash, and different forms of non-cash compensation; however, the compensation committee has not adopted formal plans or programs that allocate total compensation among these various characteristics.


35


In determining the mix and level of compensation components for our named executive officers, Mr. Littlefair typically makes recommendations to our compensation committee regarding appropriate pay. After reviewing Mr. Littlefair’s recommendations, our compensation committee makes the final determination regarding compensation mix and levels for each of our named executive officers. Although Mr. Littlefair submits recommendations to the compensation committee regarding his own proposed compensation, which the committee may taketakes under advisement, in its discretion, Mr. Littlefair does not participate in the compensation committee’s deliberations regarding his own compensation.

Mr. Littlefair’s recommendations, and the compensation committee’s decisions, regarding the mix and level of compensation components for each of our named executive officers are based on a number of factors, including, among others, the individual’s performance and contribution to our strategic plan and other business objectives; the Company’s overall performance in light of business and industry conditions; general industry trends and market reference points; the level of the individual’s responsibility; the seniority of the individual; the individual’s long-term commitment to our Company; the available pool of individuals with similar skills; retention risk for the individual; principles of pay equity and relative pay (we generally believe that executives with comparable experience, levels of responsibility and performance deserve comparable compensation, and that more experienced executives with a greater degree of responsibility and higher performance levels deserve higher levels of compensation on a relative basis); the role of each compensation component in achieving the objectives of our executive compensation program; and the compensation committee’s business judgment and experience.

Base Salary

We provide base salaries to recognize the experience, skills, knowledge, and responsibilities of our named executive officers; reward individual performance and contribution to our overall business goals; and retain our executives. The compensation committee reviews base salaries annually and relies on its judgment and discretion in determining the amount of each named executive officer’s base salary. Proposed base salaries are prepared by Mr. Littlefair and recommended to the compensation committee for its consideration and approval.


The compensation committee determined to maintain 2020 base salaries for our named executive officers at their 2019 levels. In making this conclusion the compensation committee considered Mr. Littlefair’s recommendations; the Company’s performance, in light of business and industry conditions; the compensation committee’s assessment of each executive’s performance, experience, responsibilities, work demands and tenure, as well as the retention risk associated with each executive; and the Company’s key objectives of conserving cash resources and limiting selling, general and administrative expenses.

For 2021, the compensation committee determined to maintain Mr. Littlefair’s base salary at his 2020 level (it has been at the same level since 2015) and to increase the base salaries of Messrs. Vreeland, Pratt and Corbus by 13%, 8% and 8%, respectively. Messrs. Pratt’s and Corbus’ base salaries had not increased since 2014 and Mr. Vreeland’s base salary was increased to better align his compensation with his responsibilities and the base salaries of our other senior executives.

Base salaries for our named executive officers in 2019, 2020 and 2021 are as follows:

Cash Incentives

2020

2021 Performance-Based Cash Incentive Plan and Discretionary Incentive

Our compensation committee believes cash incentives are important to focus our management on, and reward our executives for, achieving Company financial and strategic objectives on an annual basis, as well as to deliver adequate retention value when combined with our other incentive programs, which may be denominated in equity and/or designed to incentivize performance over a longer term than annually. The compensation committee has the discretion to determine performance criteria, consider factors and developments it deems relevant and award overall cash incentives in the amounts it deems appropriate.


36


Each year our compensation committee approves a performance-based cash incentive plan and pays incentives after reviewing our performance with respect to the criteria set forth in the plan. Further, our compensation committee may, in its discretion, award additional special discretionary cash incentives for extraordinary efforts or performance by our named executive officers that the compensation committee believes are not otherwise covered by the performance criteria in our performance-based cash incentive plan.

In addition, our compensation committee, in its discretion, awarded additional discretionary cash incentives to our named executive officers in the amounts set forth in the table below. Such incentives were paid for the significant strategic achievements detailed in this Compensation Discussion and Analysis which the committee determined reflected management’s efforts in leading the company through 2020 and, more importantly, effectively positioning the company for the future. The compensation committee had not awarded discretionary cash incentives since 2011.

2020 Performance-Based Cash Incentive Plan

In the first halfFebruary of 2020,2021, the compensation committee approved a performance-based cash incentive plan that included base, middle and maximum performance targets as well as “stress”for each of the quantitative performance metrics described below. This was a return to our historic incentive plan design, and, “COVID”unlike in 2020, we did not include any specific COVID-adjusted targets that attempted to consider the anticipated negative effects from the COVID-19 pandemic.

for 2021.

For 2020,2021, the total potential cash incentive award under our performance-based cash incentive plan for each of our named executive officers was based on the following (the financial performance criteria are prepared by our Chief Financial Officer based on our annual budget, as amended, and the strategic initiatives are developed by our Chief Executive Officer):

·33% was based on our adjusted EBITDA, which is a non-GAAP financial measure described below;

·25% was based on the volume of GGEs of RNG, CNG and LNG we delivered;

·22% was based on the achievement (as determined in the compensation committee’s sole discretion) of certain specified strategic initiatives; and

·20% was based on our volume margin, as defined below.


33% was based on our adjusted EBITDA, which is a non-GAAP financial measure described below;

25% was based on the volume of GGEs of RNG, CNG and LNG we delivered;

22% was based on the achievement (as determined in the compensation committee’s sole discretion) of certain specified strategic initiatives; and

20% was based on our volume margin, as defined below.
We believe this combination of objective financial performance criteria that include both revenue and profitability measures, combined with tying a portion of the incentive to the achievement of strategic objectives, appropriately incentivized the named executive officers to achieve our business objectives for 2021.
Performance Criteria.For 2020,2021, we defined the volume of GGEs of RNG, CNG and LNG we delivered as (1) the volume of GGEs we sell to our customers as fuel, plus (2) the volume of GGEs dispensed at facilities we do not own but where we provide operation and maintenance services on a per-gallon or fixed fee basis, plus (3) our proportionate share of the GGEs sold as CNG by our joint venture, Mansfield Clean Energy Partners, LLC.

For 2020,2021, we defined volume margin as gross profit margin from the volumes of RNG, CNG and LNG we delivered, excluding gross profit margin from certain royalties and from our sales of credits we generate under federal and state programs by selling RNG and conventional RNG, CNG and LNG as a vehicle fuel, divided by the volumes of RNG, CNG and LNG we delivered (where “gross profit margin” is our volume-related revenue less our volume-related cost of sales).

For 2020,2021, we defined adjusted EBITDA as net income (loss) attributable to Clean Energy, plus (minus) income tax expense (benefit), plus interest expense, minus interest income, plus depreciation and amortization expense, plus stock-based compensation expense, plus (minus) loss (income) from equity method investments, and plus (minus) any loss (gain) from changes in the fair value of derivative instruments. See page 6555 of this proxy statement for the calculation of our 20202021 adjusted EBITDA.

EBITDA, as well as a reconciliation of adjusted EBITDA to net income (loss), which is the most comparable GAAP financial measure.

For 2020,2021, our strategic initiatives included making significant progresswinning a substantial portion of Amazon’s business with respect to fueling its natural gas vehicles, securing at least 50 medium-duty truck orders, securing reauthorization of alternative fuel tax credit (“AFTC”) and working with the Zero Now program; launching a Zero Now program for medium duty trucks; creating a strategic alliance with Chevronfederal government to drive truck adoption;promote RNG initiatives, delivering 164167.6 million GGEs of RNG; contracting for at least ten million incremental gallons of supply of low CI RNG;RNG, finalizing and securing reauthorization of AFTC.

beginning to implement joint ventures with BP and Total, and pursuing hydrogen projects and RNG initiatives.

The COVID, stress, base, middle and maximum targets for the performance criteria under the incentive plan approved by our compensation committee for 2020,2021, as well as our actual performance for these criteria, are set forth in the following table:

If each of the four performance criteria are achieved at the base performance level, Mr. Littlefair would be entitled to an incentive payment equal to 70% of his target bonus, while the other named executive officers would be entitled to an incentive payment equal to 50% of their base salaries. If each of the four performance criteria are achieved at the middle (target) performance level, Mr. Littlefair would be entitled to an incentive payment equal to 100% of his target bonus, while the other named executive officers would be entitled to an incentive payment equal to 70% of their base salaries. The maximum incentive payment for Mr. Littlefair is equal to 150% of his target bonus, and the maximum incentive payment for the other named executive officers is equal to 100% of their base salaries. Payouts for performance between the base and middle performance levels and between the middle and maximum performance levels are interpolated on a straight-line basis.
Payouts.The compensation committee met in December 2020, January 2021, and February 20212022 to review our 20202021 actual performance versus the performance criteria and strategic initiative targets described above and to determine what payouts, if any, would be made under the 20202021 performance-based cash incentive plan. When evaluating our 2020 performance, the compensation committee considered the fact that the impact

Our company achieved approximately 103% of the COVID-19 pandemic onmiddle target for adjusted EBITDA, which was in-between our middle and maximum targets. This adjusted EBITDA performance resulted in an above target payout for this performance measure.

Our company achieved approximately 102% of the financialbase target for the volume performance metrics used undermeasure, which was in-between our base and middle targets. This volume performance resulted in a below target payout for this performance measure.

Our company achieved in excess of the cash incentive plan was more severe than it anticipated whenmaximum target for volume margin, which resulted in the targets were established. capped maximum payout for this performance measure.

The compensation committee determined:

·Our company achieved 99.8% of the COVID Target for adjusted EBITDA. Based on this performance and after taking account an adjustment for the unanticipated COVID-19 impacts, the compensation committee determined to providedetermined that the named executive officers made significant progress on each of the strategic initiatives, and decided that a payout equal to the middle target amount for the compensation-based adjusted EBITDA criterion.

·With respect to the volume performance criterion, the compensation committee considered, among other things, the 31.2 million GGEs of incremental fuel volumes added in 2020, including from high profile new customers such as Amazon and NY MTA, and achieving 95% of the COVID Target, and determined that based on this performance it was appropriate to provide a payout equal to 100% of the base target amount for the volume performance criterion.

·It was appropriate to provide no payout for the volume margin performance criterion. The shortfall in higher margin volumes caused by COVID-19 proved too steep to overcome, and the compensation committee determined that even after adjusting for the unanticipated COVID-19 impacts, no payout for this performance metric was warranted. We were, however, able to reduce SG&A spending to help overcome the negative effect on our gross profit margin from the lower volume margin per GGE.

·50% of the strategic initiatives were achieved, which was consistent with target level performance, and therefore it was appropriate to provide a payout equal to the middle target amount for the strategic initiatives performance criterion.

2020 Discretionary Cash Incentives

The compensation committee regarded 2020 as a pivotal year for the company with substantial achievements in strategic positioning—achievements that went well beyond the adjusted EBITDA and volume (GGEs and margin) goals of the annual incentive plan and even further beyond the specific strategic initiatives that were established as targetsperformance measure was appropriate. This payout level for the annual incentive plan. The compensation committee consideredstrategic initiatives was lower than the more than tripling ofblended payout level achieved for the company’s market value and share price during 2020 as a reflection of the pivotal actions taken, including our initiation of partnerships with Total, Chevron and bp. As a result, the compensation committee determined to pay discretionary cash incentives, giving significant weight to the following:

three financial performance measures.

·Management successfully positioned the company as a leading renewable energy company focused on the procurement and distribution of RNG and conventional natural gas, in the form of CNG and LNG, for the United States and Canadian transportation markets. The committee believes this positioning contributed in large part to the significant stock price increase we experienced in 2020 (from a 52-week low of $1.05 in March 2020 to multi-year high prices in December 2020 and a closing price of $7.86 on December 31, 2020), which continued through February 23, 2021, the date the compensation committee awarded 2020 cash incentive compensation.

·The Company’s significant efforts, led by our management, in developing, owning, and operating dairy and other livestock waste RNG projects and supplying RNG (procured from our own projects or from third parties) to our customers in the heavy- and medium-duty commercial transportation sector.

·Management effectively highlighted the company’s unique position in the marketplace: the valuable Environmental Credits associated with RNG are generated by the party that dispenses RNG into vehicle fuel tanks and we believe we now have access to more dispensers than any other market participant.

·Through management’s efforts, feedstock owners and project developers value our long operating history, strong reputation in the industry and unmatched access to fueling infrastructure and vehicle operators for certainty of Environmental Credit generation.

·We increased our RNG supply sources to over 30. We believe that we have one of the largest and most diverse supply portfolios in the RNG industry, which allows us to provide certainty of RNG supply to our vehicle operator customers.

·The company partnered with Chevron on Adopt-a-Port, an initiative that provides truck operators serving the ports of Los Angeles and Long Beach with RNG to reduce emissions. For its part, Chevron provides funding for Adopt-a-Port and supplies RNG to Clean Energy stations near the ports. Chevron’s funding allows truck operators to subsidize the cost of buying new RNG-powered trucks. We manage the program, including offering fueling services for qualified truck operators. Truck operators participating in the program, which supports the ports’ Clean Trucks Program and Clean Air Action Plan, fuel at our stations supplied with Chevron RNG. Importantly, Adopt-a-Port provides a meaningful air quality improvement for the adversely-impacted communities around the port – such communities typically have the worst air quality in the nation. As of December 31, 2020, customers had ordered 141 trucks under Adopt-a-Port, and we expect at least 310 additional trucks to be ordered in 2021.

·We struck partnerships with Total and bp giving us access to at least $345 million of capital to develop and own dairy and other livestock waste RNG production projects and build new stations for key customers that agree to fuel volume purchase requirements.

·The size and scope of our refuse business increased.

·Management effectively managed our cash and investments to enable us to repay the remaining $50.0 million of 7.5% Notes in full and having $138.5 million of cash and short-term investments at the end of 2020.

·We successfully refinanced a significant amount of NG Advantage’s debt, which we expect will save $8.2 million in debt service costs over the next three years.


Further, demand for executives with experience in alternative vehicle fuels has become acute, and the compensation committee felt it was important to ensure that we retain our executive management team.

20212022 Performance-Based Cash Incentive Plan

In February 2021,2022, the compensation committee approved our 20212022 performance-based cash incentive plan. The plan has substantially the samea similar design as our 20202021 performance-based cash incentive plan, including the discretion afforded to our compensation committee in determining performance criteria, performance targets and actual payouts, provided that such plan does not have any “stress” or “COVID” targets as thepayouts. The compensation committee determined that it was better abledecided to predict the impact of the COVID-19 pandemicintroduce a new performance measure based on our RNG volume to stress the strategic importance of this portion of our business, and this in turn resulted in different weightings for the incentive plan performance measures relative to our 2021 results. plan design.

38


Among other things, the 20212022 plan provides that the total potential incentive award for each of our named executive officers under the plan will be based on the following:

·33% will be based on our adjusted EBITDA, defined in the same manner as was used for the 2020 plan;

·25% will be based on the volume of GGEs of RNG, CNG and LNG we deliver, defined in substantially the same manner as was used for the 2020 plan;

·22% will be based on the achievement (as determined in the compensation committee’s sole discretion) of certain specified strategic initiatives; and

·20% will be based on our volume margin, defined in substantially the same manner as was used for the 2020 plan.


30% will be based on our adjusted EBITDA, defined in substantially the same manner as was used for the 2021 plan;

20% will be based on the volume of GGEs of RNG, CNG and LNG we deliver, defined in substantially the same manner as was used for the 2021 plan;

New for 2022, 10% will be based on the volume of RNG we deliver;

20% will be based on the achievement (as determined in the compensation committee’s sole discretion) of certain specified strategic initiatives; and

20% will be based on our volume margin, defined in substantially the same manner as was used for the 2021 plan.
Equity Incentives

We believe motivation of long-term performance motivation is achieved through an ownership culture that encourages performance by our named executive officers usingthrough the use of stock-based awards. Our equity incentive plans have been established to provide certain of our employees, including our named executive officers, with incentives designed to align these employees’ interests with the interests of our stockholders. In general, the compensation committee develops its equity award determinations based on its judgments as to whether thethese equity awards provided to our named executive officers are sufficient to further our ownership culture, appropriately align the interests of our named executive officers with those of our stockholders and retain, motivate, and adequately reward our executives on a long-term basis.

We have historically granted our named executive officers the following three typesa combination of equity awards under our equity incentive plans: stock options RSUs and price-vested units (“Price-Vested Units” or “PVUs”). In addition, in February 2019, ourRSUs. These awards are subject to both time-based and performance-based vesting requirements, and the compensation committee awarded a new typehas exercised its judgment on the weighting of equity awardstock options relative to our named executive officers, which we refer to as volume-vested options (“Volume-Vested Options” or “VVOs”). Each of these types of equity awards is described below.

RSUs in any given year.
Time and Performance-Based Stock Options:

·
Afford the recipient the option to purchase shares of our common stock at a stated price per share.

·
All stock option awards granted under our equity incentive plans include an exercise price equal to the closing price of our common stock on the applicable grant date, and the grant date is always on or after the date of compensation committee approval.

·      Stock
Time-based stock option awards granted to our named executive officers typically vest at a rate of 34% on the one-year anniversary of the date of grant and 33% on each subsequent anniversary until fully vested, subject to the named executive officer’s continued service for our Company at each vesting date.


The vesting of performance-based options granted to our named executive officers generally requires the achievement of objective performance targets or the attainment of a premium price per common share that is set as a multiple of the closing price of a share of common stock on the grant date. In December of 2021, the compensation committee introduced two new types of performance-based stock option awards that are described in more detail below. The vesting of performance-based options is also subject to the named executive officer’s continued service for our Company at each vesting date.


Time and Performance-Based RSUs:

·
Full-value awards that represent the contingent right to receive shares of our common stock upon achievement of stated vesting criteria.

·
Time-based RSU awards granted to our named executive officers typically vest at a rate of 34% on the one-year anniversary of the date of grant and

2020 Annual

Equity Awards

Granted in 2021

In February 2020,January 2021, the compensation committee awarded time-based RSUs and stock options to our named executive officers in the amounts set forth in the table below. The compensation committee granted stock option and RSU awards with time-based vesting in order to provide greater certainty of vesting and value while still incentivizing long-term performance over time, after taking into account the status of our named executive officers’ then-outstanding equity awards, volatility in our stock price due to general market and industry conditions, the greater value of RSUs to executives due to their full-value nature, and the need for stock price appreciation to provide any value with stock option awards. For 2020,the January grants, the mix of RSUs and stock options was determined based on the factors described above, with a target proportion of 40% of the total shares subject to each executive’s equity awards being in the form of RSUs and 60% of the total shares subject to each executive’s equity awards being in the form of stock options.

These RSUs are subject to the terms and conditions of the 2016 Plan and a Notice of Grant of Restricted Stock Unit and Restricted Stock Unit Agreement, and vest according to the typical three-year vesting schedule described above. These stock options are subject to the terms and conditions of the 2016 Plan and a Notice of Grant of Stock Option and Stock Option Agreement, have an exercise price of $2.56 per share, and vest according to the typical three-year vesting schedule described above.

Throughout the third and fourth quarters of 2021, the compensation committee met and it determined that the Company was at a critical juncture and that it was of primary importance to incentivize the named executive officers to (1) create long-term stockholder value by increasing the Company’s price per share and (2) strategically execute on expanding the Company’s RNG business over the long-term. The compensation committee decided to introduce two new types of performance-based stock option awards into our executive compensation program, and made grants of these performance-based stock option awards along with additional time-based stock options to each of the named executive officers in December. The December grants represent the largest component of each named executive officer’s 2021 compensation and are intended to provide a meaningful performance-based equity incentive over a number of years going forward to incentivize the executives to execute our transformative strategy. Although the size of the December grants was larger than our historical grants, over 50% of the grant date value of each executive’s grant (and approximately 66% of the grant date value of Mr. Littlefair’s grant) will only vest and have any value to the executives if we are able to increase the closing price of our common stock by a greater than 100% premium above the closing price on the grant date.
The first new performance-based option is structured to incentivize long-term RNG growth and the vesting of 100% of each grant is subject to the Company’s attainment of RNG supply through investment milestones. In 2021, RNG sales represented 78% of our total vehicle fuel sales. In order to achieve our five-year strategic plan and achieve our projected five-year RNG volume, revenue and income goals, we

40


believe we will need to make significant capital investments in order to increase our RNG supply through investment. The performance-based options are structured so that there are four separate vesting tranches, with each tranche requiring us to secure 15 million GGEs of RNG supply via investment in order to vest (i.e., the first tranche will vest if we secure 15 million GGEs of RNG supply via investment, the second tranche will vest if we secure an additional 15 million GGEs of RNG supply via investment for a total of 30 million GGEs, the third tranche will vest if we secure an additional 15 million GGEs of RNG supply via investment for a total of 45 million GGEs and the final tranche will vest if we secure an additional 15 million GGEs of RNG supply via investment for a total of 60 million GGEs). We believe these represent challenging multi-year goals that if the named executive officers are able to achieve, will help drive our transformative strategic plan and the achievement of our future RNG volume, revenue and income goals. Each named executive officer must also remain in continued service for our Company at each vesting date in order to vest.
The second new performance-based option was the largest component of each executive’s December grant and is structured to incentivize long-term appreciation in the value of our shares. The vesting of 100% of each grant is subject to our attainment of a stock price representing a greater than 100% premium above the closing price of a share of common stock on the grant date. In order for these performance-based options to vest, we must achieve an average closing price equal to or above $14.00 per share over a twenty consecutive trading day period. Each named executive must also remain in continued service for our Company on the vesting date in order to vest.
Each named executive officer was also awarded an additional grant of time-based options that vest according to the typical three-year vesting schedule described above.
All of these December stock options are subject to the terms and conditions of the 2016 Plan and a Notice of Grant of Stock Option and Stock Option Agreement, and have an exercise price of $6.77 per share.

As discussed above, the compensation committee spent significant time in the third and fourth quarters of 2021 evaluating the structure of our long-term equity incentive awards and designing our two new types of performance-based options. Once the design of our performance-based options was approved, the compensation committee determined to grant the named executive officers their long-term incentive awards in December of 2021 and in light of these awards has also determined to make no further long-term incentive awards in 2022. This shift in grant timing had the effect of increasing Messrs. Littlefair’s, Vreeland’s, Pratt’s and Corbus’ 2021 compensation by $6,537,500, $2,826,750, $2,826,750 and $2,941,250, respectively. Because of the December grants, the compensation committee determined it will not grant any additional equity awards to named executive officers in calendar 2022.
Change in Control and Post-Termination Severance Compensation

Our employment agreements with our named executive officers, described under “Employment Agreements” below, provide them certain benefits if their employment is terminated, including a termination following a change in control but excluding a termination by the Company for cause or a voluntary termination by the named executive officer without good reason and not following a change in control.reason. The compensation committee believes these benefits are important tools for retaining the services of our named executive officers and helping to align the interests of our named executive officers with those of our stockholders. The details and amounts of these benefits are described below under “Executive Compensation—Compensation — Potential Payments Upon Termination or Change in Control.”


41


All equity awards granted to our named executive officers after November 2014, including the RSUs and stock options awarded to our named executive officers in 2020 and 2021, to date, are subject to double-trigger vesting upon a change in control. The compensation committee previously determined to modify the standard vesting provisions of our named executive officers’ equity awards from “single-trigger” to “double-trigger” vesting in connection with a change in control because it believes double-trigger vesting more accurately reflects current market practices but still provides appropriate benefits to executives in the event of a termination in connection with a change in control, and is thus in the best interests of our Company and our stockholders. Further, we do not provide any excise tax “gross-up” payments to our executives in connection with a change in control.

Other Benefits

We appreciate the tremendous value and contributions of our employees, and we believe providing a competitive employee benefits program is one of our most important investments. As a result, we offer an employee benefits program with a wide range of plans designed to promote the health and personal welfare of all employees, including our named executive officers. Participation in these plans is generally available to all of our employees on the same basis. The Company provides minimal perquisites to executives which are noted in the description of “All Other Compensation” disclosed in the Summary Compensation Table on page 56.

Employment Agreements

We entered into employment agreements with each of our named executive officers on December 31, 2015. These employment agreements have the following key terms:

·Each employment agreement has an initial term of three years ending on December 31, 2018, and automatic renewal thereafter for additional one-year periods (unless either party provides notice of non-renewal).


·Each named executive officer is entitled to receive an annual base salary of no less than his base salary in 2015, which was the same as each named executive officer’s base salary for 2020, except that (1) Mr. Littlefair’s 2020 base salary was lower because of his voluntary election to reduce his salary by 10% in February 2015, and (2) Mr. Vreeland’s 2020 base salary was higher as a result of a salary increase from 2018 to 2019.

·Each named executive officer is eligible to receive an annual cash incentive of up to a specified percentage of his then-current annual base salary under the terms of our performance-based cash incentive plan in effect for the applicable year. Mr. Littlefair is eligible to receive 70%, 100% or 150% of $778,680 for our achievement of the base, middle and maximum performance targets, respectively, and we consider achievement of the middle performance targets to be Mr. Littlefair’s target incentive amount; each of Messrs. Vreeland, Pratt, and Corbus is eligible to receive 50%, 70% or 100% of his respective base salary for our achievement of the base, middle and maximum performance targets, respectively, and we consider achievement of the middle performance targets to be Messrs. Vreeland’s Pratt’s, and Corbus’ target incentive amount.

·Each named executive officer would be entitled to receive certain severance compensation and benefits under certain circumstances upon a termination of the named executive officer’s employment with us. The details of this severance are described below under “Executive Compensation—Potential Payments Upon Termination or Change in Control.” The employment agreements condition severance payments on a so-called “double-trigger” upon a change in control. The employment agreements also do not include any “gross-up” provision for any excise taxes that may be triggered in connection with a change in control under Sections 280G and 4999 of the Code, and instead include a “best-net” cutback provision under which benefits are reduced to avoid triggering any such excise taxes unless the after-tax benefit is greater to the named executive officer without the cutback. The compensation committee determined that these terms are appropriate because they better align our severance and change of control payment practices with current market expectations and the interests of our named executive officers with those of our stockholders, while still providing a level of benefits the compensation committee believes is fair and reasonable and maintaining the retention value of these benefits.

Each employment agreement is passed its initial three-year term and now automatically renews on December 31 for additional one-year periods (unless either party provides notice of non-renewal).

Each named executive officer is entitled to receive an annual base salary of no less than his base salary in 2015.

Each named executive officer is eligible to receive an annual cash incentive of up to a specified percentage of his then-current annual base salary under the terms of our performance-based cash incentive plan in effect for the applicable year. Mr. Littlefair is eligible to receive 70%, 100% or 150% of $778,680 for our achievement of the base, middle and maximum performance targets, respectively, and we consider achievement of the middle performance targets to be Mr. Littlefair’s target incentive amount; each of Messrs. Vreeland, Pratt, and Corbus is eligible to receive 50%, 70% or 100% of his respective base salary for our achievement of the base, middle and maximum performance targets, respectively, and we consider achievement of the middle performance targets to be Messrs. Vreeland’s Pratt’s, and Corbus’ target incentive amount.

Each named executive officer would be entitled to receive certain severance compensation and benefits under certain circumstances upon a termination of the named executive officer’s employment with us. The details of this severance are described below under “Executive Compensation — Potential Payments Upon Termination or Change in Control.” The employment agreements condition severance payments on a so-called “double-trigger” upon a change in control. The employment agreements also do not include any “gross-up” provision for any excise taxes that may be triggered in connection with a change in control under Sections 280G and 4999 of the Code, and instead include a “best-net” cutback provision under which benefits are reduced to avoid triggering any such excise taxes unless the after-tax benefit is greater to the named executive officer without the cutback. The compensation committee determined that these terms are appropriate because they better align our severance and change of control payment practices with current market expectations and the interests of our named executive officers with those of our stockholders, while still providing a level of benefits the compensation committee believes is fair and reasonable and maintaining the retention value of these benefits.
Other Compensation Policies

Executive Stock Ownership Guidelines

We believe it is important to encourage our named executive officers to hold a material amount of our common stock, which links their long-term economic interest directly to that of our stockholders. To achieve

42


this goal, we have established stock ownership guidelines applicable to our named executive officers. These guidelines provide that our Chief Executive Officer is required to own shares of our common stock valued at three times his annual base salary or more, and each of our Chief Financial Officer, Chief Operating Officer, Chief Marketing Officer, Senior Vice President, Strategic Development, and Senior Vice President, Sales, in each case if any person is appointed in such position, is required to own shares of our common stock valued at one times his annual base salary or more. Such level of ownership must be attained by the later of December 14, 2019 and five years after the date of an executive officer’s initial appointment as such. Stock options are not counted toward satisfaction of these stock ownership requirements. Executives who attain the applicable stock ownership level by the stated deadline will continue to satisfy the stock ownership requirements if the value of their stock holdings declines after such deadline solely due to a decrease in the trading price of our common stock. Each of our named executive officers had satisfied these stock ownership guidelines as of the record date for the Annual Meeting.

Hedging and Pledging of Company Securities

Our policies do not permit any of our executive officers or directors to “hedge” ownership of our securities by engaging in short sales or trading in put options, call options or other derivatives involving our securities. This means that our employees and directors may not purchase financial instruments or otherwise engage in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our equity securities. Further, our policies do not permit an executive officer or director to hold our securities in a margin account or pledge our securities as collateral for a loan unless the executive officer or director demonstrates to our satisfaction financial capacity to substitute other assets for Company securities in the event of a failure to meet a margin call or a default on the loan.


As of the date of this Proxy Statement, none of our directors or executive officers has pledged any of the shares of our common stock he or she owns.

Clawback Policy

The compensation committee has adopted a formal clawback policy regarding recoupment, or a “clawback,” of cash compensation in certain circumstances. The purpose of this clawback policy is to help ensure that executives act in the best interests of the Company and our stockholders. The clawback policy requires certain of our officers, including our named executive officers, to repay or return any cash incentive or other incentive cash compensation awarded to or received by such officer(s) in the event we issue a restatement of our financial statements due to material noncompliance with any financial reporting requirements and the restatement was caused by such officer’s fraud, intentional misconduct or gross negligence. In each case, the officer(s) would be required to repay or return the incentive cash compensation awarded to or received by the officer during the 12-month period following the filing of the erroneous financial statement at issue. Pursuant to the clawback policy, in the event of any restatement of our financial statements, the compensation committee would consider a number of factors and exercise its business judgment in determining appropriate amounts, if any, to recoup. Further, the compensation committee retains the discretion to adjust or recover awards or payments if the relevant performance measures on which they are based are restated or are otherwise adjusted in a manner that would reduce the size of the award or payment. The clawback policy applies to cash compensation awarded to our officers from and after the date of its adoption.

Tax and Accounting Effects

In designing our compensation programs, the compensation committee considers the financial impact and tax and accounting effects that each element of compensation will or may have on the Company and our executives. One such area the compensation committee considers is the tax deductibility of each component of executive compensation. Prior to December 22, 2017, when the Tax Cuts and Jobs Act of 2017 (“TCJA”) was signed into law, Section 162(m) generally prohibited us from taking a tax deduction in any tax year for compensation paid to certain executive officers that exceeded $1,000,000, unless the compensation was payable only upon the achievement of pre-established, objective performance goals under a plan approved by our stockholders. As a result, we believe certain stock option RSU and PVURSU awards we granted to our named executive officers before the impact of the TCJA have qualified as performance-based compensation under Section 162(m), although there is no guarantee that such equity awards, or any

43


other performance-based compensation paid to our named executive officers, qualify as such. Under the TCJA, the exception for performance-based compensation under Section 162(m) has been repealed, so that the $1,000,000 limit on tax deductions in a tax year generally applies to anyone serving as our chief executive officer or our chief financial officer at any time during a taxable year as well as our top three other highest-compensated executive officers serving at fiscal year-end. These changes generally apply beginning in 2018, but generally do not apply to compensation provided pursuant to a binding written contract in effect on November 2, 2017 that is not modified in any material respect after that date. The compensation committee will continue to monitor developments under the TCJA, and will continue to consider steps that might be in our best interests to comply with Section 162(m), including after the impact from the TCJA. It is the compensation committee’s present intention to seek to structure executive compensation so that it will be deductible to the maximum extent permitted by applicable law, which means administering performance-based equity awards that were granted in 2017 or earlier in accordance with Section 162(m), as amended by the TCJA, in order to preserve their tax deductibility to the greatest extent possible; however, the compensation committee reserves the discretion to make any executive compensation decisions that it considers to be in the best interests of our Company and our stockholders, including to award compensation that may not be deductible or to amend existing compensation arrangements in a manner that could limit their deductibility.

The amounts shown in this column represent the grant date fair value of awards granted in each of the periods calculated in accordance with Financial Accounting Standards Board’s Accounting Standards Codification Topic 718, “Compensation  Stock Compensation” (“​(“FASB ASC 718”). For a discussion about the valuation models and assumptions used to calculate the fair value of these awards, see note 13 to the consolidated financial statements included in the Annual Report. TheFor the RNG-based performance options granted in December of 2021, the grant date fair value is reported based on the probable outcome of the VVO awards grantedapplicable performance conditions as determined on the grant date, which results in 2019 under FASB ASC 718 isa grant date fair value for these options as follows: Mr. Littlefair ($572,500), Mr. Vreeland ($343,500), Mr. Pratt ($343,500) and Mr. Corbus ($458,000). If we achieve the same athighest level of performance for the maximumRNG-based performance options, the grant date fair value would increase to the following amounts: Mr. Littlefair ($1,145,000), Mr. Vreeland ($687,000), Mr. Pratt ($687,000) and probable performance levels.

Mr. Corbus ($916,000).

Employment Agreements

On December 31, 2015, we entered into an employment agreement with each of our named executive officers. See the description under “Compensation Discussion and Analysis—Analysis — Employment Agreements” and below under “Potential Payments Upon Termination or Change in Control” for more information.

Pension Benefits, Non-Qualified Defined Contribution and Other Deferred Compensation Plans

We do not have any defined-benefit plans that provide for payments or other benefits to our named executive officers at, following or in connection with their retirement. We also do not have any non-qualified defined contribution plans or other deferred compensation plans that provide for the deferral of compensation on a basis that is not tax-qualified.

Potential Payments Upon Termination or Change in Control

The narrative and tables below describe the amount of compensation to be paid to our named executive officers in the event of a termination of employment or a change in control. The amount of compensation payable to each of our named executive officers upon a voluntary termination, voluntary termination for good reason, involuntary without cause termination, failure by us to renew the named executive officer’s employment agreement upon its expiration, for-cause termination, change in control of our Company, termination in connection with a change in control and termination due to disability or death is shown in tabular format. Except as otherwise noted, the amounts shown in these tables assume that each such termination or change in control was effective as of December 31, 2020,2021, and thus are estimates of the amounts that would be paid to our named executive officers upon an actual termination or change in control because such amounts could only be determined at the time of such an actual termination or change in control. The amounts shown in these tables are based on the terms of each named executive officer’s employment agreement with us and the terms of agreements relating to each named executive officer’s outstanding equity awards.


Severance Compensation under Employment Agreements

Pursuant to the terms of the employment agreement for each named executive officer:

·
If we terminate a named executive officer without “cause” (as​(as such term is defined in the employment agreement), if a named executive officer resigns for “good reason” (as​(as such term is defined in the employment agreement) or if we do not renew the employment agreement before expiration of the term or any renewal term, then the named executive officer would be entitled to (1) a lump-sum payment of an amount equal to the sum of (A) his annual base salary earned through the date of termination and any annual cash incentive earned for the prior year to the extent not previously paid, (B) any compensation previously deferred by the named executive officer (together with any accrued interest or earnings thereon), (C) 150% of one year’s then-current annual base salary, (D) 150% of his previous year’s annual cash incentive actually earned under our performance-based cash

49


incentive plan, and (E) any vacation pay accrued and not paid as of the date of termination; (2) after the end of the calendar year in which the termination occurs, a lump-sum payment of an amount equal to the annual cash incentive that would be payable to the named executive officer under our performance-based cash incentive plan in respect of such year (based on the criteria applicable for that year) without any pro-rating; and (3) continuing participation, at our expense, for a period of one year from the date of termination in the benefit programs in which the named executive officer was enrolled at the time of termination.

·
If we terminate any named executive officer’s employment without cause or do not renew his employment agreement within six months before or one year after the date of a “change in control” (as such term is defined in the employment agreement), or if a named executive officer resigns for good reason within six months before or one year after the date of the change in control, then the named executive officer would be entitled to the severance compensation described above, except that the lump-sum payment described in (1) above for all named executive officers except Mr. Littlefair would consist of 225% of his then-current annual base salary, 225% of his previous year’s annual cash incentive actually earned under our performance-based cash incentive plan, and the amounts described in (A), (B) and (E); and the lump-sum payment described in (1) above for Mr. Littlefair would consist of 300% of his then-current annual base salary, 300% of his previous year’s annual cash incentive actually earned under our performance-based cash incentive plan, and the amounts described in (A), (B) and (E).

·
If any named executive officer ceases to be an employee due to death or disability, then the named executive officer would be entitled to the amounts described in (1)(A), (B) and (E) and (2) above, except that the amount described in (2) above would be pro-rated based on the number of weeks during the last fiscal year during which the named executive officer was an employee.

·
If, at any time that our common stock is not listed or quoted on a national securities exchange or an over-the-counter quotation system, (i) the employment of either of Messrs. Littlefair or Pratt is terminated for cause, we would be entitled, at our option, to repurchase all or a portion of our stock owned by him, or (ii) the employment of either of these named executive officers is terminated due to death or disability, we would be required to repurchase all of our stock owned by him.

In consideration of the receipt of any of the severance compensation described above and as a precondition to their receipt, each named executive officer would be required to execute and deliver, and not revoke, a release in favor of us in the form attached to his employment agreement. For purposes of the tables below, we have assumed that the amounts described in (1)(A) and (B) above have already been paid to the applicable named executive officer or are $0.


For purposes of each such named executive officer’s employment agreement:

·      “Cause”
“Cause” means (1) the named executive officer committing a material act of dishonesty against us, (2) the named executive officer being convicted of a felony involving moral turpitude or (3) the named executive officer committing a material breach of his confidentiality, trade secret, non-solicitation or invention assignment obligations under his employment agreement.

·      “Good
“Good reason” means the named executive officer resigns from his employment after we (1) have materially diminished the named executive officer’s duties, authority, responsibility, annual base salary or annual incentive compensation opportunity, (2) materially breach the employment agreement; (3) change the person to whom the named executive officer reports, or (4) change the location of the named executive officer’s principal place of employment

·      “Change
“Change in control” means (1) any “person” (as​(as defined or referred to in Section 3(a)(9) and/or 13(d)(1), et seq. of the Exchange Act and the associated rules of the SEC promulgated thereunder), other than an existing stockholder of the Company as of January 1, 2006, is or becomes the “beneficial owner” (as​(as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 40% or more of the combined voting power of our then-outstanding securities, or (2) a merger or consolidation of the Company in which its voting securities immediately before the merger or consolidation do not represent, or are not converted into securities that represent, a majority of the combined voting power of all voting securities of the surviving entity immediately after the merger or consolidation, or (3) a sale, lease, exchange or other transfer (in one transaction or a

50


series of related transactions) of all or substantially all of the assets of the Company or a liquidation or dissolution of the Company, or (4) individuals who, as of the date of the employment agreement, constitute the Company’s board of directors (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Company’s board of directors; provided that, other than in connection with an actual or threatened proxy contest, any individual who becomes a director subsequent to the date of the employment agreement whose election, or nomination for election by the stockholders of the Company, was approved by the vote of at least a majority of the directors then in office shall be deemed a member of the Incumbent Board.

Vesting of PVUs

The terms of the PVUs granted to our named executive officers are subject to the following provisions regarding changes in the employment status of a named executive officer: (i) the PVU award will be forfeited in full if the named executive officer’s employment with the Company is terminated for cause (as defined in his employment agreement) or voluntarily by the named executive officer before the fourth anniversary of the PVU’s grant date (“Termination Date”); (ii) if the named executive officer’s employment is terminated by the Company without cause (as defined in his employment agreement) and the Stock Price Hurdle is subsequently satisfied before the Termination Date, the Time-Vested Percentage (as defined in the PVU award agreement) of the PVUs will vest on the date the Stock Price Hurdle is satisfied; (iii) if the named executive officer ceases to be an employee due to death or disability, the Time-Vested Percentage of the PVUs will immediately vest; and (iv) if the Company experiences a “change in control,” as defined in the Amended and Restated 2006 Equity Incentive Plan (“2006 Plan”) or the 2016 Plan, as applicable, before the Termination Date, 100% of the PVUs will vest if the per share consideration received by holders of common stock in connection with such change in control equals or exceeds the Stock Price Hurdle. For purposes of the PVU award agreements, “Time-Vested Percentage” means (1) the quotient of (A) the number of full months that have elapsed from the PVU’s grant date up to the date of the holder’s termination of service, divided by (B) forty-eight, multiplied by (2) one hundred, provided that the Time-Vested Percentage shall never exceed one hundred.

For purposes of the tables below, no amounts are shown for the vesting of PVUs because none of our named executive officers held any outstanding PVUs as of December 31, 2020.

Vesting of Options VVOs and RSUs

The terms of the option and VVO awards granted to our named executive officers provide that all unvested options and VVOs will be forfeited if the named executive officer’s employment with the Company is terminated for cause (as defined in his employment agreement) or voluntarily by the named executive officer before their applicable vesting date, that all unvested options and VVOs will vest in full if the named executive officer’s employment is terminated by the Company without cause (as defined in his employment agreement), and that all vested options and VVOs will generally continue to be exercisable for three months after the date of any such termination. The terms of the RSU awards granted to our named executive officers provide that all unvested RSUs will be forfeited if the named executive officer’s employment with the Company is terminated by the Company for cause or voluntarily by the named executive officer before their applicable vesting date, and that all unvested RSUs will vest in full if the named executive officer’s employment is terminated by the Company without cause or if the named executive officer ceases to be an employee due to death or disability before their applicable vesting date.


If the Company experiences a “change in control,” as defined in the 2006 Plan or the 2016 Plan, as applicable, then each such named executive officer’s option VVO and RSU awards that are outstanding on the date that immediately precedes the change in control will (A) if such awards are not assumed or replaced by the successor company in the change in control, immediately vest in full and, if applicable, become fully exercisable on the date of the change in control, or (B) if such awards are assumed or replaced by the successor company in the change in control but the named executive officer’s employment is terminated by the successor company without cause or by the named executive officer for good reason within 12 months following the change in control (based on the definitions of “cause” and “good reason” in his employment agreement with us), immediately vest in full and, if applicable, become fully exercisable on the date of such termination.

For purposes of the tables below, the “spread” value (i.e., the excess of $7.86$6.13 per share, which was the closing price of our common stock on December 31, 2020,2021, over the applicable option exercise price) of unvested option awards that were “in the money” on December 31, 20202021 is presented. For VVOs, the tables below assume that all unvested VVOs will vest.

Pay Ratio

We are required by applicable SEC rules to disclose the annual total compensation of our Chief Executive Officer, the median annual total compensation of all of our other employees, and the ratio of these two amounts.


53


In determining the median annual total compensation of our employees other than our Chief Executive Officer, we started by preparing a list of all such employees as of December 31, 20202021 and each such employee’s taxable earnings for 20202021 as reflected in our payroll records, which generally consists of salary; regular, hourly, and overtime wages; commissions; incentives and other miscellaneous earnings. This list includes all our employees on such date (except solely for our Chief Executive Officer), whether employed on a full-time, part-time, seasonal or temporary basis and wherever located, resulting in 445443 employees who are all located in the United States. For any such employees who are permanently employed (in other words, who are not employed on a seasonal or temporary basis) and who joined the Company after January 1, 2020,2021, this list reflects 20202021 taxable earnings on an annualized basis. We then ordered the employees in this list based on the amounts of their 20202021 taxable earnings, selected the single employee at the midpoint of the re-ordered list, and calculated the amount of this single midpoint employee’s annual total compensation using the methodology required by SEC rules for calculating the total compensation of our named executive officers as reported in the Summary Compensation Table above. The annual total compensation for our median employee was $86,048.90$130,294, and the annual total compensation for our Chief Executive Officer was $1,826,353.$10,811,193. We estimate the ratio of the annual total compensation of our Chief Executive Officer to the median annual total compensation of all our other employees is 21.283 to 1.

We believe this pay ratio is a reasonable estimate calculated in a manner consistent with applicable SEC rules. In light of the many different methodologies, exclusions, estimates and assumptions companies are permitted to use in determining an estimate of their respective pay ratios, as well as the differing employment and compensation practices and industry standards that impact these ratios, our estimated pay ratio information may not be comparable to the pay ratio information reported by other companies, and we discourage the use of this information as a basis for comparison between companies. Neither our compensation committee nor our management used our pay ratio information in making compensation decisions for 20202021 or 2021.

2022.

Risks Related to Compensation Policies and Practices

The compensation committee regularly monitors and considers whether our overall compensation programs, including our executive compensation program, create incentives for employees to take excessive or unreasonable risks that could materially harm our Company. Although risk-taking is a necessary part of any business, the compensation committee focuses on aligning the Company’s compensation policies with the long-term interests of the Company and its stockholders and avoiding short-term rewards for management decisions that could pose long-term risks to the Company. Although a portion of our executive compensation plan is performance-based, which could motivate risk-taking, we do not believe our overall compensation structure encourages excessive or unnecessary risk-taking. We believe our approach to goal-setting, the mix of different types of compensation, payouts at multiple levels of performance, evaluation of performance results, and allowance for compensation committee discretion in determining award types, levels and payouts assist in mitigating these risks, as follows:

·
Our compensation structure includes a combination of compensation vehicles, including a competitive base salary and benefits generally available to all of our employees, equity awards to incentivize long-term performance and align the interests of our employees with those of our stockholders, annual cash incentives to reward executives for achieving Company objectives, and change in control and post-termination severance compensation to encourage retention of our key executives.

·
To discourage excessive or unnecessary risk-taking, for 2020,2021, payouts to each named executive officer under our performance-based cash incentive plan were based on four distinct performance metrics, each with material weighting. Additionally, the compensation committee retains the discretion to increase or decrease payouts under this incentive plan as it deems appropriate.

·
To help mitigate risks of overpayment due to fraudulent, intentional or grossly negligent errors, our clawback policy permits us, under certain circumstances, to recover certain cash compensation in the event of a restatement of our financial statements or excess payments of performance-based compensation in the event of a restatement or other adjustment of the performance measures on which the payments are based.

We further believe that our internal legal and financial controls appropriately mitigate the probability and potential impact of an individual employee committing our Company to a harmful long-term business transaction in exchange for a short-term compensation benefit.


54


Based on the factors described above, we believe our 20202021 compensation programs do not create risks that are reasonably likely to have a material adverse effect on our Company.

DIRECTOR COMPENSATION

Overview

We use cash and equity compensation to attract and retain qualified candidates to serve on our Board. The amount and type of cash and equity compensation awarded to non-employee directors is determined by the compensation committee each year in its sole discretion. In setting non-employee director compensation, the compensation committee considers a variety of factors, including the significant amount of time that our directors spend in fulfilling their duties to our Company, as well as the level of experience and skill required of the members of the Board. We have also awarded compensation to individual non-employee directors or directors serving in certain positions on our Board or its committees in recognition of outstanding service or efforts on the Company’s behalf. Further, in setting director compensation, our compensation committee considers that a director’s independence may be jeopardized if director compensation and perquisites exceed customary levels, if the Company makes charitable or political contributions to organizations with which a director is affiliated or if the Company enters into consulting contracts with (or provides other indirect forms of compensation to) a director or an organization with which a director is affiliated. Directors who are our employees receive no additional compensation for their services as directors. In addition, for 20202021 and 2022 each of Messrs. Charleux, Maurisse, and Montantême,Wolffsheim and for 2021 each of Messrs. Charleux and MaurisseMs. Boissy-Rousseau voluntarily waived histheir right to receive compensation for histheir services as a director of our Company.

After reviewing the factors described above and others that it considered relevant, the compensation committee approved the non-employee director compensation program described below for 20202021 and 2022 compensation.
Cash
For 2021 compensation.

Cash

For 2020 and 2021,2022, our non-employee directors (other than Messrs. Charleux, MontantêmeMaurisse and Maurisse)Wolffsheim and Ms. Boissy-Rousseau) received (or will receive) the following cash compensation:

·
All of our non-employee directors receive base cash compensation of $60,000 per year;

·
Audit committee members (other than the Chairman) receive an additional $2,500 in cash compensation per year in recognition of their additional responsibilities;

·
The Chairman of the audit committee receives an additional $10,000 per year in recognition of his additional responsibilities; and

·
The Chairman of the Board receives an additional $60,000 per year in recognition of his additional responsibilities.

Equity

For 2020, each non-employee director (other than Messrs. Montantême and Charleux) received an option award for a number of shares equal to a grant date fair value of approximately $63,840 and $79,380 for Mr. Weil only as his grant date was in August 2020, all of which were fully vested upon grant. For 2021, each

Each non-employee director (other than Messrs. Charleux, Maurisse and Maurisse)Wolffsheim and Ms. Boissy-Rousseau) received an option award on January 21, 2021 for a number of shares equal to a grant date fair value of approximately $579,000 and an option award on December 7, 2021 for a number of shares equal to a grant date fair value of approximately $438,000, except for Ms. Paskett who received only an option award on December 21, 2021 for a number of shares equal to a grant date fair value of approximately $420,000, all of which will be vested in one year.year from each option award date. The compensation committee chose to award options (rather than RSUs or a combination of RSUs and options) in 2020 and 2021 based on, among other things, its determination that our non-employee directors preferred option awards and the compensation committee’s desire to limit depletion of the 2016 Plan’s share limit (each share of common stock issued in respect of RSUs awarded under the 2016 Plan is counted against the share limit as 1.5 shares, whereas each share of common stock issued in respect of options awarded under the 2016 Plan is counted against the share limit as 1.0 share).

The December option awards were granted to the non-employee directors in lieu of making any annual long-term equity awards to the directors in 2022. Because of the December grant timing and the way the SEC’s disclosure rules work, the director compensation table below effectively includes two-years’ worth of

56


equity awards, which we believe overstates the compensation received by the non-employee directors in 2021. The chart below illustrates the value of the two equity awards granted to the non-employee directors in 2021.

$579,000$438,000(1)

The grant date value of Ms. Paskett’s award was $420,000.
Because of the December grants, the Board does not intend to grant any non-employee directors any additional equity awards in calendar 2022.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Related Party Transactions

Except as described below, since January 1, 2020,2021, there has not been, nor is there currently proposed, any transaction or series of similar transactions in which we were or are to be a participant, in which the amount involved exceeds $120,000 and in which any of our directors, executive officers, holders of more than 5% of our common stock or any immediate family member of any of the foregoing had or will have a direct or indirect material interest. This does not include employment compensation or compensation for Board service, which are described elsewhere in this Proxy Statement.

Relationships with TOTALTotalEnergies and its Affiliates

Total

During 2021, the Company recognized revenue of $3.3 million and $0.4 million, respectively, related to LNG sold to TotalEnergies and its affiliates in the ordinary course of business and AFTC credits associated therewith.
The Company purchased $0.6 million in parts and materials from TotalEnergies in the ordinary course of business during 2021.
TotalEnergies Agreements

On May 9, 2018, we entered into a stock purchase agreement (the “Purchase Agreement”) with TMS for the sale and issuance to TMS of up to 50,856,296 shares of our common stock, representing approximately 25% of the outstanding shares of our common stock and the largest ownership position of our Company, for a per share purchase price of $1.64 and an aggregate cash purchase price of $83.4 million. The Total Private PlacementTotalEnergies private placement closed on June 13, 2018.

Pursuant to the Purchase Agreement, TMS has the right to designate up to two individuals to serve as directors on our Board. Subject to certain limited conditions as described in the Purchase Agreement, including compliance with our governing documents and all applicable laws, rules and regulations, we will be obligated to appoint or nominate for election as directors of our Company the individuals so designated by TMS and, from and after such appointment or election, either (1) appoint one of these individuals to serve on the audit committee of the Board and any other Board committees that may be formed from time to time for the purpose of making decisions that are strategically significant to our Company, or (2) nominate another individual as an observer of such Board committees, who is to be invited to attend all meetings of such committees in a non-voting observer capacity. TMS’ rights and our obligations relating to these designees and observers continue until (and if) (a) with respect to TMS’ right to designate two individuals to serve as directors on our Board and an optional observer to serve on certain Board committees, TMS’ voting power is less than 16.7% but more than 10.0%, and (b) with respect to TMS’ right to designate one individual to serve as a director on our Board and an optional observer to serve on certain Board committees, TMS’ voting power is less than 10.0%, in each case measured in relation to the votes then entitled to be cast in an election of directors by our stockholders.

The Purchase Agreement also provides that, until the later of May 9, 2020 or such date when TMS ceases to hold more than 5% of our common stock then outstanding, among other similar undertakings and subject to customary conditions and exceptions, TMS and its affiliates are prohibited from purchasing shares of our common stock or otherwise pursuing transactions that would result in TMS owning more than 30% of our equity securities without the approval of our Board.

In connection with the Purchase Agreement on May 9, 2018, we and all of our then-directors and officers entered into a voting agreement with TMS. Pursuant to the voting agreement, each of our directors and officers agreed to vote all shares of our common stock presently or hereafter owned or controlled by such director or officer, in any vote of our stockholders that may be held from time to time, in favor of the election of the individuals designated by TMS to serve as directors on our Board. Each of our directors and officers has also granted to TMS a proxy to vote all such shares in accordance with the terms of the voting agreement. For each of our directors and officers party to the voting agreement, the voting obligations contained in the agreement continue from and after, and for so long as, TMS’ director designation rights

60


are in effect, as described above, and such director or officer continues to serve in such capacity for our Company (other than Mr. Pickens, one of our former directors and co-founders, who continues to be bound by these voting obligations even after he has ceased to serve as such for our Company) and continues to hold shares of our common stock.

Pursuant to the Purchase Agreement, we also entered into a registration rights agreement with TMS on June 13, 2018. Pursuant to the registration rights agreement, we became obligated to, at our expense, (1) file one or more registration statements with the SEC to cover the resale of the shares of our common stock purchased by TMS under the Purchase Agreement, (2) use our commercially reasonable efforts to cause all such registration statements to be declared effective in a timely manner, (3) use our commercially reasonable efforts to maintain the effectiveness of such registration statements until all such shares are sold or may be sold without restriction pursuant to applicable rules under the Securities Act, and (4) make and keep available adequate current public information and timely file with the SEC all required reports and other documents until all such shares are sold or may be sold without restriction. If such registration statements are not filed or declared effective as described above or any such effective registration statements subsequently become unavailable for more than 30 days in any 12-month period while they are required to maintained as effective, then we would be required to pay liquidated damages to TMS equal to 0.75% of the aggregate purchase price for the shares remaining eligible for such registration rights each month for each such failure (up to a maximum of 4.0% of the aggregate purchase price for the shares remaining eligible for such registration rights each year).


Credit Support Agreement

On January 2, 2019, we entered a credit support agreement (“CSA”(as amended, the “CSA”) with TotalTotalEnergies Holdings USA Inc. (“THUSA”), a wholly owned subsidiary of TOTAL.TotalEnergies. Under the CSA, THUSA agreed to enter into a guaranty agreement (“Guaranty”) pursuant to which it has guaranteed our obligation to repay up to $100.0 million in term loans (“Loans”) and interest thereon in accordance with a term credit agreement we have entered into with an unaffiliated third party (the “Lender”). In consideration for the commitments of THUSA under the CSA, we are required to pay THUSA on a quarterly basis, a guaranty fee at a rate per annumquarter equal to 10%2.5% of the average aggregate Loan amount for the preceding calendar quarter.

Following any payment by THUSA to the Lender under the Guaranty, we would be obligated to immediately pay to THUSA the full amount of such payment plus interest on such amount at a rate equal to LIBOR plus 1.0%. In addition, we would be obligated to pay and reimburse THUSA for all reasonable out-of-pocket expenses it incurs in the performance of its services under the CSA, including all reasonable out-of-pocket attorneys’ fees and expenses incurred in connection with the payment to the Lender under the Guaranty or any enforcement or attempt to enforce any of our obligations under the CSA.

The CSA includes customary representations and warranties and affirmative and negative covenants by us. In addition, upon the occurrence of a “Trigger Event” and during its continuation, THUSA may, among other things: elect not to guarantee additional Loans; declare all or any portion of the outstanding amounts we owe THUSA under the CSA to be due and payable; and exercise all other rights it may have under applicable law. Each of the following events constitutes a Trigger Event: we default with respect to any payment obligation under the CSA; any representation or warranty made by us in the CSA was false, incorrect, incomplete or misleading in any material respect when made; we fail to observe or perform any material covenant, obligation, condition or agreement in the CSA; or we default in the observance or performance of any agreement, term or condition contained in any other agreement with THUSA or an affiliate of THUSA.

As security for our obligations under the CSA, on January 2, 2019, we entered into a pledge and security agreement with THUSA and delivered a collateral assignment of contracts to THUSA, pursuant to which we collaterally assigned to THUSA all fueling agreements we enter into with participants in our Zero Nowtruck financing program. In addition, on January 2, 2019, we entered into a lockbox agreement with THUSA and PlainsCapital Bank, under which we granted THUSA a security interest in the cash flow generated by the fueling agreements we enter into with participants in the Zero Now program. Until the occurrence of a Trigger Event or Fundamental Trigger Event (as described below) under the CSA, we have the freedom to operate in the normal course and there are no restrictions on the flow of funds in and out of the lockbox account established pursuant to the lockbox agreement. Upon the occurrence of a Trigger Event under the CSA, all funds in the lockbox account will be: first, used to make scheduled debt repayments of Loans and interest thereon; and second, released to us. Further, upon the occurrence of a “Fundamental

61


Trigger Event” under the CSA and during its continuation, in addition to exercising any of the remedies available to THUSA upon the occurrence of a Trigger Event as described above: all participants in the Zero Now program would pay amounts owed under their fueling agreements with us directly into the lockbox account; under a “sweep” mechanism, all cash in the lockbox account would be used to prepay all outstanding Loans; no other disbursements from the lockbox account could be made without THUSA’s consent; and THUSA would retain dominion over the lockbox account and the funds in the account would remain as security for our payment and reimbursement obligations under the CSA. Each of the following events constitutes a Fundamental Trigger Event: we default in the observance or performance of any agreement, term or condition contained in the term credit agreement governing the Loans that would constitute an event of default thereunder, up to or beyond any grace period provided in such agreement, unless waived by the Lender; we default in the observance or performance of any agreement, term or condition contained in any evidence of indebtedness other than such term credit agreement, and the effect of such default is to cause, or permit the holders of such indebtedness to cause, acceleration of indebtedness in an aggregate amount for all such collective defaults of $20.0 million or more; voluntary and involuntary bankruptcy and insolvency events; and the occurrence of a change of control of our Company.


The CSA will terminate following the later of: the payment in full of all of our obligations under the CSA; and the termination or expiration of the Guaranty following the maturity date of the last outstanding Loan or December 31, 2023, whichever is earlier.

During 2021, we paid TotalEnergies $0.3 million related to the guaranty fee under the CSA.
Commodity Swap Arrangements

In October 2018, we entered into commodity swap arrangements with TotalTotalEnergies Gas & Power North America, an affiliate of TOTALTotalEnergies and THUSA, intended to manage diesel price fluctuation risks related to the natural gas fuel supply commitments we expect to make in our anticipated fueling agreements with fleet operators that participate in our Zero Nowtruck financing program, which arrangements cover five million diesel gallons of natural gas fuel volume annually from April 2019 through June 2024.

The TotalTotalEnergies JV Agreement contemplates that the TotalTotalEnergies JV will invest up to $400 million of equity in production projects, and TotalTotalEnergies and the Company each committed to initially provide $50 million for the TotalTotalEnergies JV.

Annex A
Proposed 2022 Employee Stock Purchase Plan
CLEAN ENERGY FUELS CORP. 4675
2022 EMPLOYEE STOCK PURCHASE PLAN
The following constitute the provisions of the 2022 Employee Stock Purchase Plan (the “Plan”) of Clean Energy Fuels Corp (the “Company”).
1.   Purpose.   The purpose of the Plan (as defined below) is to provide Employees (as defined below) of the Company (as defined below) and its Designated Parents (as defined below) or Subsidiaries (as defined below) with an opportunity to purchase Common Stock (as defined below) of the Company through accumulated payroll deductions. It is the intention of the Company to have the Plan qualify as an “employee stock purchase plan” under Section 423 of the Code (as defined below) and the applicable regulations thereunder. The provisions of the Plan, accordingly, shall be construed so as to extend and limit participation in a manner consistent with the requirements of that section of the Code.
2.   Definitions.   As used herein, the following definitions shall apply:
(a)   “Administrator” means either the Board or a committee of the Board that is responsible for the administration of the Plan as is designated from time to time by resolution of the Board.
(b)   “Applicable Laws” means the legal requirements relating to the administration of employee stock purchase plans, if any, under applicable provisions of federal securities laws, state corporate and securities laws, the Code and the applicable regulations thereunder, the rules of any applicable stock exchange or national market system, and the rules of any foreign jurisdiction applicable to participation in the Plan by residents therein.
(c)   “Board” means the Board of Directors of the Company.
(d)   “Code” means the Internal Revenue Code of 1986, as amended.
(e)   “Commission” means the U.S. Securities and Exchange Commission.
(f)   “Common Stock” means the common stock of the Company, par value of $0.0001 per share, and such other securities or property as may become the subject of Options pursuant to an adjustment made under Section 18.
(g)   “Compensation” means an Employee’s base salary from the Company or one or more Designated Parents or Subsidiaries, including such amounts of base salary as are deferred by the Employee: (i) under a qualified cash or deferred arrangement described in Section 401(k) of the Code; or (ii) to a plan qualified under Section 125 of the Code. “Compensation” does not include overtime, bonuses, annual awards, other incentive payments, reimbursements or other expense allowances, fringe benefits (cash or non-cash), moving expenses, deferred compensation, contributions (other than contributions described in the first sentence) made on the Employee’s behalf by the Company or one or more Designated Parents or Subsidiaries under any employee benefit or welfare plan now or hereafter established, and any other payments not specifically referenced in the first sentence. The Administrator may establish, in its discretion and on a uniform and nondiscriminatory basis, a different definition of Compensation prior to an Offer Date for all Options to be granted on such Offer Date, which definition may vary among Participants who are employed by the Company or different Designated Parents or Subsidiaries.
(h)   “Corporate Transaction” means any of the following transactions, unless the Administrator provides otherwise:
(i)   any merger or consolidation in which the Company shall not be the surviving entity (or survives only as a subsidiary of another entity the stockholders of which did not own all or substantially all of the Common Stock in substantially the same proportions as immediately before such transaction);

A-1


(ii)   the sale of all or substantially all of the Company’s assets to any other person or entity (other than a wholly-owned subsidiary of the Company);
(iii)   the acquisition of beneficial ownership of a controlling interest of fifty percent (50%) or more (including power to vote) in the outstanding shares of Common Stock by any person or entity (including a “group” as defined by or under Section 13(d)(3) of the Exchange Act);
(iv)   the dissolution or liquidation of the Company;
(v)   a contested election of directors, as a result of which or in connection with which the persons who were members of the Board before such election or their nominees cease to constitute a majority of the Board; or
(vi)   any other event specified, prior to the commencement of an Offer Period, by the Board.
Notwithstanding the foregoing, the term “Corporate Transaction” shall not include any underwritten public offering of shares registered under the Securities Act of 1933, as amended.
(i)   “Designated Parents or Subsidiaries” means any of the Parents or Subsidiaries, which have been designated by the Administrator from time to time as eligible to participate in the Plan.
(j)   “Effective Date” means June 30, 2022. However, should any Parent or Subsidiary become a Designated Parent or Subsidiary after such date, then the Administrator, in its discretion, shall designate a separate Effective Date with respect to the employee-participants of such Designated Parent or Subsidiary.
(k)   “Employee” means any individual, including an officer or director, who is an employee of the Company or a Designated Parent or Subsidiary for purposes of Section 423 of the Code. For purposes of the Plan, the employment relationship shall be treated as continuing intact while the individual is on sick leave or other leave of absence approved by the individual’s employer. Where the period of leave exceeds three (3) months and the individual’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship will be deemed to have terminated on the day that is three (3) months and one (1) day following the start of such leave, for purposes of determining eligibility to participate in the Plan.

(m)   “Exercise Date” means the last day of each Offer Period.
(n)   “Fair Market Value” means, as of any date, the value of Common Stock determined as follows:
(i)   If the Common Stock is listed on one or more established stock exchanges, its Fair Market Value shall be the closing sales price for such stock (or the closing bid, if no sales were reported) as quoted on the principal exchange or system on which the Common Stock is listed (as determined by the Administrator) on the date of determination (or, if no closing sales price or closing bid were reported on that date, as applicable, on the last trading date such closing sales price or closing bid was reported);
(ii)   If the Common Stock is regularly quoted on an automated quotation system (including the OTC Bulletin Board) or by a recognized securities dealer, but selling prices are not reported, its Fair Market Value shall be the mean between the high bid and low asked prices for the Common Stock on the date of determination (or, if no such prices were reported on that date, on the last date such prices were reported), as reported in The Wall Street Journal or such other source as the Administrator deems reliable; or
(iii)   In the absence of an established market for the Common Stock of the type described in (i) and (ii), above, its Fair Market Value thereof shall be determined by the Administrator in good faith.
(o)   “New Exercise Date” has the meaning set forth in Section 18(b).

A-2


(p)   “Offer Period” means an Offer Period established pursuant to Section 4 hereof.
(q)   “Offering” means an offer under this Plan of an Option that may be exercised during an Offer Period. For purposes of the Plan, all Employees eligible to participate pursuant to Section 3 will be deemed to participate in the same Offering unless the Administrator otherwise determines that Employees of the Company or one or more Designated Parent or Subsidiary will be deemed to participate in separate Offerings, in which case the Offerings will be considered separate even if the dates of each such Offering are identical and the provisions of the Plan will separately apply to each Offering. To the extent permitted by Section 1.423-2(a)(1) of the Treasury regulations issued under Section 423 of the Code, the terms of each Offering need not be identical provided that the terms of the Plan and the Offering together satisfy Sections 1.423-2(a)(2) and (a)(3) of such Treasury regulations.
(r)   “Offering Date” means the first day of each Offer Period.

(t)   “Parent” means a “parent corporation” of the Company, whether now or hereafter existing, as defined in Section 424(e) of the Code.
(u)   “Participant” means an Employee of the Company or Designated Parent or Subsidiary who has enrolled in the Plan as set forth in Section 5(a).
(v)   “Purchase Price” means an amount equal to 85% of the Fair Market Value of a share of Common Stock on the Exercise Date.
(w)   “Reserves” means, as of any date, the sum of: (1) the number of shares of Common Stock covered by each then outstanding Option under the Plan which has not yet been exercised; and (2) the number of shares of Common Stock which have been authorized for issuance under the Plan but not then subject to an outstanding Option.
(x)   “Subsidiary” means a “subsidiary corporation” of the Company, whether now or hereafter existing, as defined in Section 424(f) of the Code.
3.   Eligibility.
(a)   General.   Subject to the further limitations in Sections 3(b) and 3(c), any individual who is an Employee on a given Offering Date shall be eligible to participate in the Plan for the Offer Period commencing with such Offering Date. No individual who is not an Employee shall be eligible to participate in the Plan.
(b)   Limitations on Grant and Accrual.   Any provisions of the Plan to the contrary notwithstanding, no Employee shall be granted an Option under the Plan: (i) if, immediately after the grant, such Employee (taking into account stock owned by any other person whose stock would be attributed to such Employee pursuant to Section 424(d) of the Code) would own stock and/or hold outstanding options to purchase stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any Parent or Subsidiary; or (ii) which permits the Employee’s rights to purchase stock under all employee stock purchase plans of the Company and its Parents or Subsidiaries to accrue at a rate which exceeds Twenty-Five Thousand Dollars (US$25,000) worth of stock (determined at the Fair Market Value of the shares at the time such Option is granted) for each calendar year in which such Option is outstanding at any time. The determination of the accrual of the right to purchase stock shall be made in accordance with Section 423(b)(8) of the Code and the regulations thereunder.
(c)   Other Limits on Eligibility.   Notwithstanding Subsection (a), above, the Company, in its discretion, may determine prior to the Offering Date for an Offer Period that the following Employees shall not be eligible to participate in the Plan for such Offer Period: (i) Employees whose customary employment is 20 hours or fewer per week; (ii) Employees whose customary employment is for not more than five (5) months in any calendar year; (iii) Employees who have been employed for less than

A-3


two (2) years; or (iv) highly compensated Employees (within the meaning of Section 414(q) of the Code). Notwithstanding Subsection (a), above, unless otherwise determined prior to the Offering Date for an Offer Period, the following Employees shall not be eligible to participate in the Plan for such Offer Period: Employees who are citizens or residents of a non-U.S. jurisdiction (without regard to whether he or she is also a citizen of the United States or a resident alien (within the meaning of Section 7701(b)(1)(A) of the Code)) if his or her participation is prohibited under the laws of the applicable non-U.S. jurisdiction or if complying with the laws of the applicable non-U.S. jurisdiction would cause the Plan or an Offering to violate Section 423 of the Code.
4.   Offer Periods.
(a)   Unless otherwise determined by the Administrator, the Plan shall be implemented through consecutive Offer Periods of six (6) months’ duration commencing each January 1 and July 1 following the Effective Date during the term of the Plan until the earlier of: (i) the maximum number of shares of Common Stock available for issuance under the Plan shall have been purchased; or (ii) the Plan shall have been sooner terminated in accordance with Section 19.
(b)   A Participant shall be granted a separate Option for each Offer Period in which he or she participates. The Option shall be granted on the Offering Date and shall be automatically exercised on the last day of the Offer Period.
(c)   Except as specifically provided herein, the acquisition of Common Stock through participation in the Plan for any Offer Period shall neither limit nor require the acquisition of Common Stock by a Participant in any subsequent Offer Period.
5.   Participation.
(a)   An eligible Employee may become a Participant in the Plan by submitting an authorization of payroll deduction (using such form or method (including electronic forms) as the Administrator may designate from time to time) as of a date in advance of the Offering Date for the Offer Period in which such participation will commence, as required by the Administrator for all eligible Employees with respect to a given Offer Period.
(b)   Payroll deductions for a Participant shall commence with the first partial or full payroll period beginning on the Offering Date and shall end on the last complete payroll period during the Offer Period, unless sooner terminated by the Participant as provided in Section 10.
6.   Payroll Deductions.
(a)   At the time a Participant enrolls in the Plan, the Participant shall elect to have payroll deductions made during the Offer Period in amounts between one percent (1%) and not exceeding ten percent (10%) of the Compensation which the Participant receives during the Offer Period, subject to the limitation set forth in Section 3(b).
(b)   All payroll deductions made for a Participant shall be credited to the Participant’s account under the Plan and will be withheld in whole percentages only. A Participant may not make any additional payments into such account.
(c)   A Participant may discontinue participation in the Plan as provided in Section 10, or may increase or decrease the rate of payroll deductions during the Offer Period by submitting notice of a change of status (using such form or method (including electronic forms) as the Administrator may designate from time to time) authorizing an increase or decrease in the payroll deduction rate. Any increase or decrease in the rate of a Participant’s payroll deductions shall be effective as soon as administratively practicable following the date of the request. A Participant’s payroll deduction authorization (as modified by any change of status notice) shall remain in effect for successive Offer Periods unless terminated as provided in Section 10. The Administrator shall be authorized to limit the number of payroll deduction rate changes during any Offer Period.
(d)   Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) herein, a Participant’s payroll deductions shall be decreased to 0%. Payroll

A-4


deductions shall recommence at the rate provided in such Participant’s payroll deduction authorization, as amended, when permitted under Section 423(b)(8) of the Code and Section 3(b), unless such participation is sooner terminated by the Participant as provided in Section 10.
7.   Grant of Option.   On the Offering Date, each Participant shall be granted an Option to purchase (at the applicable Purchase Price) shares of Common Stock; provided: (i) that such Option shall be subject to the limitations set forth in Sections 3(b), 6 and 12 and (ii) that such Option shall be subject to such other terms and conditions (applied on a uniform and nondiscriminatory basis), as the Administrator shall determine from time to time. Exercise of the Option shall occur as provided in Section 8, unless the Participant has withdrawn pursuant to Section 10, and the Option, to the extent not exercised, shall expire on the last day of the Offer Period with respect to which such Option was granted. Notwithstanding the foregoing, shares subject to the Option may only be purchased with accumulated payroll deductions credited to a Participant’s account in accordance with Section 6. In addition, to the extent an Option is not exercised on the Exercise Date, the Option shall lapse and thereafter cease to be exercisable.
8.   Exercise of Option.   Unless a Participant withdraws from the Plan as provided in Section 10, the Participant’s Option for the purchase of shares of Common Stock will be exercised automatically on the Exercise Date, by applying the accumulated payroll deductions in the Participant’s account to purchase the number of full shares subject to the Option by dividing such Participant’s payroll deductions accumulated prior to the Exercise Date and retained in the Participant’s account as of the Exercise Date by the applicable Purchase Price. No fractional shares will be purchased; any payroll deductions accumulated in a Participant’s account which are not sufficient to purchase a full share shall be returned to the Participant as soon as administratively practicable, without interest. In addition, any amount remaining in a Participant’s account following the purchase of shares on the Exercise Date due to the application of Section 423(b)(8) of the Code or Section 7, shall be returned to the Participant and shall not be carried over to the next Offer Period. During a Participant’s lifetime, a Participant’s Option to purchase shares hereunder is exercisable only by the Participant.
9.   Delivery.   After each Exercise Date on which a purchase of shares occurs, as soon as administratively practicable, the Company shall, in its discretion, either deliver to each Participant a certificate representing the shares of Common Stock purchased upon exercise of his or her Option, provide for the crediting of such shares in book entry form in the name of the Participant, or provide for an alternative arrangement for the delivery of such shares to a broker or recordkeeping service for the benefit of the Participant. In the event the Company is required to file a registration statement to issue any such certificate or otherwise deliver such shares, the Company will seek to obtain such authority. If the Company is unable to obtain from any such commission or agency authority which counsel for the Company deems necessary for the lawful issuance of any such certificate or other delivery of such shares, or if for any other reason the Corporation cannot issue or deliver shares of Common Stock and comply with Applicable Laws, the Corporation shall be relieved from liability to any Participant except that the Company shall return to each Participant to whom such shares cannot be issued or delivered the amount of the balance credited to his or her account that would have otherwise been used for the purchase of such shares.
10.   Withdrawal; Termination of Employment.
(a)   A Participant may, by giving notice to the Company (using such form or method (including electronic forms) as the Administrator may designate from time to time), either: (i) withdraw all but not less than all the payroll deductions credited to the Participant’s account and not yet used to exercise the Participant’s Option under the Plan; or (ii) terminate future payroll deductions, but allow accumulated payroll deductions to be used to exercise the Participant’s Option under the Plan at any time. If the Participant elects withdrawal alternative (i) described above, all of the Participant’s payroll deductions credited to the Participant’s account will be paid to such Participant as soon as administratively practicable after receipt of notice of withdrawal, such Participant’s Option for the Offer Period will be automatically terminated, and no further payroll deductions for the purchase of shares will be made during the Offer Period. If the Participant elects withdrawal alternative (ii) described above, no further payroll deductions for the purchase of shares will be made during the Offer Period, all of the Participant’s payroll deductions credited to the Participant’s account will be applied to the exercise of the Participant’s Option on the Exercise Date (subject to Sections 3(b), 6, 7 and 12), and all remaining accumulated payroll deduction amounts shall be returned to the Participant. If a Participant withdraws

A-5


from an Offer Period, payroll deductions will not resume at the beginning of the succeeding Offer Period unless the Participant enrolls in such succeeding Offer Period as provided in Section 10(b). The Administrator may, in its discretion and on a uniform and nondiscriminatory basis, specify procedures for withdrawal.
(b)   A Participant’s termination from Plan participation during the Offer Period precludes the Participant from again participating in this Plan during that Offer Period. However, such termination shall not have any effect upon his or her ability to participate in any succeeding Offer Period, provided that the applicable eligibility and participation requirements are again then met. A Participant’s termination from Plan participation shall be deemed to be a revocation of that Participant’s authorization of payroll deduction and such Participant must submit a new authorization of payroll deduction (using such form or method (including electronic forms) as the Administrator may designate from time to time) to resume Plan participation in any succeeding Offer Period.
(c)   Upon termination of a Participant’s employment relationship (as described in Section 2(l)) prior to the Exercise Date, the payroll deductions credited to such Participant’s account during the Offer Period will be returned to such Participant or, in the case of his/her death, to the person or persons entitled thereto under Section 14, and such Participant’s Option will be automatically terminated without exercise of any portion of such Option.
(d)   For purposes of this Plan, if a Designated Parent or Subsidiary ceases to be a Designated Parent or Subsidiary, each person employed by such Designated Parent or Subsidiary will be deemed to have terminated employment for purposes of this Plan and will no longer be an eligible Employee under the Plan, unless such person continues as an eligible Employee in respect of the Company or another Designated Parent or Subsidiary.
11.   Interest.   No interest shall accrue on the payroll deductions credited to a Participant’s account under the Plan.
12.   Stock.
(a)   The maximum number of shares of Common Stock which shall be made available for sale under the Plan shall be two million five hundred thousand shares (2,500,000) shares, subject to adjustment upon changes in capitalization of the Company as provided in Section 18. If the Administrator determines that on the Exercise Date for an Offer Period the number of shares with respect to which Options are to be exercised exceeds: (x) the number of shares then available for sale under the Plan; or (y) the number of shares available for sale under the Plan on the Offering Date for such Offer Period, the Administrator may disallow the purchase of any shares, and may make a pro rata allocation of the shares remaining available for purchase on such Offering Date or Exercise Date, as applicable, and shall either continue the Offer Period then in effect or terminate the Offer Period then in effect pursuant to Section 19, below. Such allocation method shall be “bottom up,” with the result that all Option exercises for one share shall be satisfied first, followed by all exercises for two shares, and so on, until all available shares have been exhausted. Any amount remaining in a Participant’s payroll account following such pro rata allocation shall be returned to the Participant and shall not be carried over to any Offer Period, as determined by the Administrator.
(b)   A Participant will have no interest in or voting right with respect to shares covered by the Participant’s Option until such shares are purchased on the Participant’s behalf on the exercise date in accordance with the applicable provisions of the Plan. No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date of such purchase.
(c)   Shares to be delivered to a Participant under the Plan will be registered by the Company in the name of the Participant.
13.   Administration.   The Plan shall be administered by the Administrator, which shall have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility, to adjudicate all disputed claims filed under the Plan, and to designate separate Offerings for the eligible Employees of the Company and one or more Designated Parents or Subsidiaries, in which case the Offerings will be considered separate even if the dates of each such Offering are identical and the provisions

A-6


of the Plan will separately apply to each Offering. Every finding, decision and determination made by the Administrator shall, to the full extent permitted by Applicable Law, be final and binding upon all persons. Notwithstanding anything else contained in this Plan to the contrary, the Administrator may also adopt rules, procedures, separate offerings, or sub-plans applicable to particular Designated Parents or Subsidiaries or locations, which separate offerings or subplans may be designed to be outside the scope of Section 423 of the Code and need not comply with the otherwise applicable provisions of this Plan. The Administrator may delegate ministerial non-discretionary functions to third parties, including individuals who are officers or employees of the Company or Designated Parents or Subsidiaries. In making any determination or in taking or not taking any action under this Plan, the Administrator may obtain and may rely on the advice of experts, including professional advisors to the Company. The Administrator will not be liable for any action, omission or decision under the Plan taken, made or omitted in good faith.
14.   Designation of Beneficiary.
(a)   Each Participant will file a designation (using such form or method (including electronic forms) as the Administrator may designate from time to time) of a beneficiary who is to receive any shares and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death. If a Participant is married and the designated beneficiary is not the spouse, spousal consent shall be required for such designation to be effective.
(b)   Such designation of beneficiary may be changed by the Participant at any time by written notice. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Administrator), the Administrator shall deliver such shares and/or cash to the spouse (or domestic partner, as determined by the Administrator) of the Participant, or if no spouse (or domestic partner) is known to the Administrator, then to the issue of the Participant, such distribution to be made per stirpes (by right of representation), or if no issue are known to the Administrator, then to the heirs at law of the Participant determined in accordance with Section 27.
15.   Transferability.   No payroll deductions credited to a Participant’s account, Options granted hereunder, or any rights with regard to the exercise of an Option or to receive shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution, or as provided in Section 14) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Administrator may, in its sole discretion, treat such act as an election to withdraw funds from an Offer Period in accordance with Section 10.
16.   Use of Funds.   All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions or hold them exclusively for the benefit of Participants. All payroll deductions received or held by the Company may be subject to the claims of the Company’s general creditors. Participants shall have the status of general unsecured creditors of the Company. Any amounts payable to Participants pursuant to the Plan shall be unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the Employee Retirement Income Security Act of 1974, as amended. The Company shall retain at all times beneficial ownership of any investments which the Company may make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Participant account shall not create or constitute a trust or fiduciary relationship between the Administrator, the Company or any Designated Parent or Subsidiary and a Participant, or otherwise create any vested or beneficial interest in any Participant or the Participant’s creditors in any assets of the Company or a Designated Parent or Subsidiary. The Participants shall have no claim against the Company or any Designated Parent or Subsidiary for any changes in the value of any assets that may be invested or reinvested by the Company with respect to the Plan.
17.   Reports.   Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to Participants at least annually, which statements will set forth the amounts of payroll deductions, the Purchase Price, the number of shares purchased and the remaining cash balance, if any.

A-7


18.   Adjustments Upon Changes in Capitalization; Corporate Transactions.
(a)   Adjustments Upon Changes in Capitalization.   Subject to any required action by the stockholders of the Company, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, proportionally adjust the Reserves, the Purchase Price, the maximum number of shares that may be purchased in any Offer Period, as well as any other terms that the Administrator determines require adjustment, for: (i) any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock; (ii) any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; or (iii) any other transaction with respect to Common Stock, including a corporate merger, consolidation, acquisition of property or stock, separation (including a spin-off or other distribution of stock or property), reorganization, liquidation (whether partial or complete) or any similar transaction; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment, if any, shall be made by the Administrator and its determination shall be final, binding and conclusive. Except as the Administrator determines, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason hereof shall be made with respect to, the Reserves and the Purchase Price.
(b)   Corporate Transactions.   In the event of a proposed Corporate Transaction, each Option under the Plan shall be assumed by such successor corporation or a parent or subsidiary of such successor corporation, unless the Administrator, in the exercise of its sole discretion and in lieu of such assumption, determines to shorten the Offer Period then in progress by setting a new Exercise Date (the “New Exercise Date”). If the Administrator shortens the Offer Period then in progress in lieu of assumption in the event of a Corporate Transaction, the Administrator shall notify each Participant in writing at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the Participant’s Option has been changed to the New Exercise Date and that either:
(i)   the Participant’s Option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offer Period as provided in Section 10; or
(ii)   the Company shall pay to the Participant on the New Exercise Date an amount in cash, cash equivalents, or property as determined by the Administrator that is equal to the excess, if any, of (x) the Fair Market Value of the shares subject to the Option over (y) the Purchase Price due had the Participant’s Option been exercised automatically under Subsection (b)(i) above. In addition, all remaining accumulated payroll deduction amounts shall be returned to the Participant.
(c)   For purposes of Section 18(b), an Option granted under the Plan shall be deemed to be assumed if, in connection with the Corporate Transaction, the Option is replaced with a comparable Option with respect to shares of capital stock of the successor corporation or Parent thereof. The determination of Option comparability shall be made by the Administrator prior to the Corporate Transaction and its determination shall be final, binding and conclusive on all persons.
(d)   The Administrator may adopt such valuation methodologies for outstanding Options as it deems reasonable in the event of a cash or property settlement and, without limitation on other methodologies, may base such settlement solely upon the excess (if any) of the amount payable upon or in respect of such event over the Purchase Price of the Option.
(e)   In any of such events, the Administrator may take such action sufficiently prior to such event to the extent that the Administrator deems the action necessary to permit the Participant to realize the benefits intended to be conveyed with respect to the underlying shares in the same manner as is or will be available to stockholders generally.
(f)   Without limiting the generality of Section 13, any good faith determination by the Administrator as to whether an adjustment is required in the circumstances pursuant to this Section 18, and the extent and nature of any such adjustment, shall be conclusive and binding on all persons.

A-8


19.   Amendment or Termination.
(a)   The Administrator may at any time and for any reason terminate or amend the Plan. Except as provided in Section 18, no such termination can adversely affect Options previously granted, provided that the Plan or the Offer Period then in effect may be terminated by the Administrator by establishing a new Exercise Date for such Offer Period if the Administrator determines that the termination of the Plan or such Offer Period is in the best interests of the Company and its stockholders. Except as provided in Section 18 and this Section 19, no amendment may make any change in any Option theretofore granted which adversely affects the rights of any Participant without the consent of affected Participants. With respect to any amendment to increase the total number of shares of Common Stock under the Plan, the Administrator shall have discretion to disallow the purchase of any increased shares of Common Stock for the Offer Period in existence prior to such increase. To the extent necessary to comply with Section 423 of the Code (or any successor rule or provision or any other Applicable Law), the Company shall obtain stockholder approval of any amendment in such a manner and to such a degree as required.
(b)   Without stockholder consent and without regard to whether any Participant rights may be considered to have been “adversely affected,” the Administrator shall be entitled to limit the frequency and/or number of changes in the amount withheld during Offer Periods, determine the length of any future Offer Period and frequency of purchases within each Offer Period, determine whether future Offer Periods shall be consecutive or overlapping, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, establish or change Plan or per Participant limits on share purchases, designate from time to time the Parents and/or Subsidiaries whose employees may be eligible to participate in the Plan, change the service and other qualification requirements for eligible Employees under the Plan (subject to the requirements of Section 423(b) of the Code and applicable rules and regulations thereunder), establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable foreign jurisdictions, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable and which are consistent with the Plan, in each case to the extent consistent with the requirements of Code Section 423 and other Applicable Laws.
20.   Notices.
(a)   All notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Administrator at the location, or by the person, designated by the Administrator for the receipt thereof.
(b)   Any person who has acquired shares under this Plan shall give prompt written notice to the Company of any sale or other transfer of the shares if such sale or transfer occurs (a) within the two-year period after the Offering Date of the Offer Period with respect to which such shares were acquired, or (b) within the twelve-month period after the Exercise Date of the Offer Period with respect to which such shares were acquired.
21.   Conditions Upon Issuance of Shares.   Shares shall not be issued with respect to an Option unless the exercise of such Option and the issuance and delivery of such shares pursuant thereto shall comply with all Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a condition to the exercise of an Option, the Company may require the Participant to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned Applicable Laws or is otherwise advisable. In addition, no Options shall be exercised or shares issued hereunder before the Plan has been approved by stockholders of the Company as provided in Section 23.
22.   Term of Plan.   The Plan shall become effective upon the Effective Date. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 19.

A-9


23.   Stockholder Approval.   Continuance of the Plan shall be subject to approval by the stockholders of the Company within twelve (12) months before or after the date the Plan is adopted. Such stockholder approval shall be obtained in the degree and manner required under Applicable Laws and the applicable provisions of the Company’s charter and bylaws.
24.   No Employment Rights.   The Plan does not, directly or indirectly, create in any employee or class of employees any right with respect to continuation of employment by the Company or a Designated Parent or Subsidiary, and it shall not be deemed to interfere in any way with such employer’s right to terminate, or otherwise modify, an employee’s employment at any time.
25.   No Effect on Retirement and Other Benefit Plans.   Except as specifically provided in a retirement or other benefit plan of the Company or a Designated Parent or Subsidiary, participation in the Plan shall not be deemed compensation for purposes of computing benefits or contributions under any retirement plan of the Company or a Designated Parent or Subsidiary, and shall not affect any benefits under any other benefit plan of any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is related to level of compensation. The Plan is not a “Retirement Plan” or “Welfare Plan” under the Employee Retirement Income Security Act of 1974, as amended.
26.   Effect of Plan.   The provisions of the Plan shall, in accordance with its terms, be binding upon, and inure to the benefit of, all successors of each Participant, including, without limitation, such Participant’s estate and the executors, administrators or trustees thereof, heirs and legatees, and any receiver, trustee in bankruptcy or representative of creditors of such Participant.
27.   Governing Law.   The Plan is to be construed in accordance with and governed by the internal laws of the State of Delaware without giving effect to any choice of law rule that would cause the application of the laws of any jurisdiction other than the internal laws of the State of Delaware to the rights and duties of the parties, except to the extent the internal laws of the State of Delaware are superseded by the laws of the United States. Should any provision of the Plan be determined by a court of law to be illegal or unenforceable, the other provisions shall nevertheless remain effective and shall remain enforceable.
28.   Dispute Resolution.   The provisions of this Section 28 shall be the exclusive means of resolving disputes arising out of or relating to the Plan. The Company and the Participant, or their respective successors (the “parties”), shall attempt in good faith to resolve any disputes arising out of or relating to the Plan by negotiation between individuals who have authority to settle the controversy. Negotiations shall be commenced by either party by notice of a written statement of the party’s position and the name and title of the individual who will represent the party. Within thirty (30) days of the written notification, the parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to resolve the dispute. If the dispute has not been resolved by negotiation, the parties agree that any suit, action, or proceeding arising out of or relating to the Plan shall be brought in the United States District Court for the Central District of California (or should such court lack jurisdiction to hear such action, suit or proceeding, in a California state court in Orange County) and that the parties shall submit to the jurisdiction of such court. The parties irrevocably waive, to the fullest extent permitted by law, any objection the party may have to the laying of venue for any such suit, action or proceeding brought in such court. THE PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR PROCEEDING. If any one or more provisions of this Section 28 shall for any reason be held invalid or unenforceable, it is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable.
